That's a pretty good explanation for mule sterility, and I'll add to that: Mules also have an odd number of chromosomes. You see, a horse has 64 chromosomes, while donkeys have 62. That leaves mules in the middle with 63. Because it's an odd number, it can't split evenly for sexual reproduction. The video kinda touched on that with the "different deck of cards" analogy. :) Also on that note, the total number of recorded cases of a female mule giving birth within the past 500 years have been 60. Let that sink in: 60 in 500 years, versus millions of mules within that same time span. That's why it's just easier to say that mules are sterile, without having to explained just how miraculously rare it is for a molly (the word for a female mule) to be fertile.
Sorry to show up 9 months late, but I am a bit confused as to why hybrids such as Pomarine Jaegers and Lonicera flys are still able to breed like normal. I doubt that rare thing that happens to mules is happening every time the Jeager or the fly breeds.
Your description of miosis is wrong...students might get confused ...fix it ...don't edit a video like this with that much flaw Sex cells are different they are formed by taking each set of chromosomes then swaping a bunch of cards( crossing over in profaze-1 stage of Miosis-1) between decks... then they decks splitting up(miosos 1) ..... then each of deck duplicate them and they break up....and in this way it creates 4 cells where each of them has 1 complete deck of cards...

Big cat hybrids are strange because all male hybrids are sterile, while females are fertile (though they have cubs pretty infrequently). I've personally always wondered if it were possible for the descendent of a big cat hybrid of a liger for example to have perfectly normal lion descendants, and how many generations it would take before the male descendants of said hybrid to regain fertility, or if they would at all. Like how many generations would it take for that one tiger ancestor to just not matter in the bigger genetic picture.
That's what I would like to know. I hear even the quarter mix hybird males are sterile. I'm not sure about a 1/8 or 1/16 mix. Be interesting if two 1/8 tigers,7/8 lions could reproduce. Might create a different type of lion. Might be possible for some culbs to come out with stripes.

The looks and temperament of that foal would potentially be different than if, instead, the mule's horse mother mated with that same stallion and had a foal with the exact same DNA. I just looked up "hinny" because I remembered that being mentioned in a book I once read as somehow related to donkeys and mules, but didn't remember how. Well, mules come from a male donkey and a female horse, hinnies come from a female donkey and a male horse, and they're worth distinguishing because not only are hinnies rarer but they also tend towards somewhat different phenotypes than mules do. Apparently, researchers think this is probably due to two main things: 1.) Genes from different sources being expressed differently-- meaning, I believe, genes from a male parent versus a female parent being expressed differently even if they're otherwise the same; I could be wrong though, I didn't look into it further. This, of course, doesn't apply to our two theoretical foals, who would have identical genomes from effectively the same source. 2.) Conditions in the womb-- such as, say, the size of the womb, and any differences in the hormones running through it (even the same mare could have different hormone conditions in one pregnancy than the next, but the difference between species would be much, much greater). Which certainly would apply. So the foal would be a horse, but might not be the horse its genetics would suggest. Given the precedent of mule versus hinny, this could wind up assigned a new name of its own. Of course, I'm not at all an expert. This should all be taken with a grain of salt. What would be really interesting would be to see if it bred true. Potentially it could... different womb size and other conditions in the resulting horse than if the mule had never been involved could lead to the same general result in the next generation, which could be stable or could get less and less over further generations. So, thank you KvaGram for accidentally causing this thought experiment.

The weirdest of all are beefaloes, which not only can reproduce despite their parents having very different numbers of chromosomes of wildly different sizes, they manage to keep genetic material from BOTH parents in their offspring.
I'm curious to find out how a hybrid could sort its genes to allow for hemiclonal transmission. Could it be an instance of a sex cell being lucky and just ending up that way, or is there more to it?
I'm not sure I agree. You're probably right in the end, but I would like to try an order of magnitude calculation of possible gametes vs. number of hybrids ever. I'm sure that the former is much much higher, but just wanted to investigate it before I check it off the list.
Makes me wonder how often this occurs with non-hybrids. Was it ever observed there? Given that there isn't somehow something super special about hybrid species specifically that allows for this, it ought to happen with essentially any species.
And then there are those rare cases where the parents still are genetically close enough for the resulting hybrids to somehow still be fertile, like, I think, with some bears, as well as with some canine combinations
nope. I'm not just talking about dog+dog but also, say, dog+wolf, etc. I think Grizzly + Polar bear has a pretty surprisingly high success chance of causing fertile offsprings.
Kram1032 That is because they are not a different species a dog and wolf are the same species called Canis and a crizzly and polar bear are also the same species called Ursus. they are a variation or we classify them as races not different species.

wait, if a female mule who is fertile always passes on the mom's horse genes, can a female mule give birth to a pure horse if the dad was also a horse?
Kitty Kat when a male horse reproduces with a female donkey, their offspring is called a hinny rather than a mule. these are far less common and there’s only ONE recorded hinny that’s given birth o_o
They did not allow them to be born though, it should be said that a ton of birds do have teeth And they look extremely reptile ish due to it XD Well it is more their beaks and tongues, similar but not regarded as "teeth".

0:34 its possible for checkens to have teeth cuz checkens hold an anciant gene that comes from dinosaurs and only scientists can activate it and make checkens have teeth Edit: i meant chickens but im keeping that XD
but but but, some scientist guy bred a chicken with teeth by reverse genetic engineering... um, genetic engineering evolution in the reverse?... umm.... I whatever you call it for back breeding dormant traits into a species. Also, pigs fly, in airplanes with humans sometimes. though I've never seen a fish climb a tree, I've seen pictures of fish in trees after a rain storm.
Actually, Mules CAN have babies, and not just because of discarding the father's genes. It's just extremely rare for a mule to foal at all, let alone without discarding the father's genes. It helps to consider that if you shuffle two decks together there's always a chance of drawing a non-repeating deck. We know this is the case because modern humans have a small number of genes from other non-human species such as neanderthals. If they just discarded the genes of the father it wouldn't have been possible for the genes to cross the species barrier. Despite being difficult, occasionally the hybrids would be able to breed with each other or humans. Due to the fact that there were more humans, and that it is apparently more likely to successfully breed a hybrid with a human than another hybrid, this explains why the genes became part of the common gene pool for all of humanity. To be more specific, only one mule family was genetically tested in 2007 and only because the mule gave birth to a foal not once, but twice - so akin to lightning striking twice. In that case, in that case only, it was determined to be due to “hemiclonal transmission" - or the mare ignoring the male's genes as if they didn't exist. This is the only case this has ever been observed in mammals - in just a single individual - so it's very much premature to assume it applies to all cases, just that it's a better explanation in cases of repeated births. Also, Chickens do have the genes for alligator teeth and sometimes are conceived with them through an Atavism, but because Chickens lost the gene required to break out of the eggs with teeth they all die when it occurs, but it's technically only one mutation away from having teeth. and there are fish that fly and skip on mud, so while I've never seen one climb a tree it wouldn't be impossible and might be a good place for a fish to build a nest of clay if evolutionary pressure pushes it that way. The only real impossibility would seem to be the flying pigs, because they would need wings and adapted bone structure.
Pigs do fly when we transport livestock on airplanes, all terrestrial vertebrates are technically fish, and the ancestors of chickens had teeth. (French people also say "when chickens have teeth")
I never knew that mules were a mix of a horse and a donkey. I thought mule was just another word referring to a donkey. I always heard the idiom, "stubborn as a mule." And thought it referred to just a donkey. Very cool to learn.
Well, if it makes you feel any better, I majored in biology in college and I don’t recall ever learning about this in genetics. Of course the teacher was awful so I didn’t learn much of anything from genetics. Good thing I didn’t want to be a geneticist!
A jenny is a female donkey. (Jacks and Jennies). Horses are stallions and mares. A cross between a jackass and a mare is a mule, while a stallion and a jenny is a hinny.
0:37 all of these have happened surprisingly! Mules very very rarely have foals, the occasional tornado or human intervention can cause pigs to ‘fly’, all amniotes are descended from fish so a monkey is technically a tree climbing fish, and many birds had teeth in the Cretaceous!
1. evolution isn't real 2. the video explained that they're made from a donkey and a horse, but aren't even technically a species because its a hybrid.
dang, im in Canada and i always hear and say "When the queen dies" 😂 gonna have to stop saying it if it ever happens but, lord knows that ladys gonna out live even me
Chickens actually have teeth, but due to epigenetic factors, they are shrunken down to a minuscule size where they are fused together and thus become unnoticeable.
The reason the pet cloning industry failed is not only because it's super expensive but more importantly the animals were different. Humans can only clone an animals appearance, but it will never be possible to clone an animals soul. So to answer the q at the end, no, your cloned cat would not be the same as Yardley. It would look similar (even then with a variation or two such as a white hair that your old cat didn't have) but it would 100% behave differently. If your cat always made a cute noise and sat by the radiator, the new cat could be silent and choose to sit on the window sill etc. Yardley may have been peaceful, new cat might be crazy behaving. Add to that, the ill health and shorter life span of cloned animals. Yep it failed, and thank goodness! Humans already do incredibly negative things to animals. Human selective breeding of animals have created animals worldwide that suffer needlessly with health issues etc. Criminal, really.
Here's an interesting factoid about adolescent male dolphins. They gang up on and rape teenage female dolphins! Did someone say dolphins were really intelligent?

"When Americans say"... a centuries-old Scottish proverb
America - taking credit for other people's inventions since 1776.
So are you saying that Americans don't say it?
Well Americans are a bunch of immigrants that hates other immigrants
+won1853 You're a moron. There is a difference between immigrants and illegal immigrants. There are plenty of people who went through the work of legally coming into the country, why should someone else just get to walk past everyone else working to legally immigrate to the US?
And racism towards legal immigrants is also very high in the US. Hell you have a presidential candidate calling for a ban of all Muslims entering the country.
Wow mules are foal of surprises
Goddammit Barb!
This comment was punny.
Your pun gave me MULtiple breathing problem
badum tssssss
ASS. That is all.
Very well done, I've never seen such a simplified version of such a complex topic.
Umm I'm not gonna lie I read the title "why can't Mules have barbies" 😶
WE ARE NOT GENDER NORMS
MULES MAY PLAY WITH WHAT THEY WISH
You can put a mule on a barbie, just cut em up first, marinade, lather with sauce, and use charcoal, propane is gross
Mules cant have Barbie's because they get jealous of their hair
I read it why cant moms have babies
Sniper Death Hawk my neckbeard radar is going crazy
wait, if a female mule who is fertile always passes on the mom's horse genes, can a female mule give birth to a pure horse if the dad was also a horse?
If the dad was also a horse, then their offspring wouldn't be a mule, but a horse
Heh.
Wait, I think what was meant is if a mule mated with a horse and the mule's mother was a horse then the mule will sometimes give birth to a horse.
I have no idea.my brain hurts.from genes and female mules giving birth is impossible wtf is going through my head.
Kitty Kat when a male horse reproduces with a female donkey, their offspring is called a hinny rather than a mule. these are far less common and there’s only ONE recorded hinny that’s given birth o_o
In Turkish, there is no saying like "when fish climbs tree".
„balik ağaca tırmanınca.”
i feel like I’ve heard someone say that, but at the same time it’s like i never heard of it before.. very strange lmao
Eeve •̀ᄉ•́ I found that we use it as “Balık kavağa çıkınca” , “ when fish climbs poplar(?) tree”
Same with Nigeria
Is there maybe a saying like "When willow bears grapes".
Because we use it in Bosnia and we havea lot of cultural similarities.
Mystery Man I have never heard of it before
0:35 In Ireland, something that is almost never seen is referred to as being “as rare as hen’s teeth.”
Scientists have actually made a chicken with teeth..
And there are some fish that climb trees. Some species of mudskipper, I think.
Well, apparently birds put climbing perch in trees... close enough?
+TheAnon26 Then the time is ripe for flying pigs!
They did not allow them to be born though, it should be said that a ton of birds do have teeth And they look extremely reptile ish due to it XD Well it is more their beaks and tongues, similar but not regarded as "teeth".
Edit: There is actually a mutant gene in chickens that can create teeth without outside help, but said mutation rarely seems to survive if ever.
Scientists have made a chicken that developed velociraptor snouts. Chickens are dinosaurs, and it's not hard to activate latent genes.
The mule's offspring is its half sibling

"This means that each female mule's offspring was genetically also her half-siblings". Very relatable if you're from Alabama

When a female horse and a male donkey have have a baby it's called a mule, when a female donkey and a male horse have a baby it's called a hinny.

Hahaha. If I tell you I’ll have to .....well you know.
No no stay
but but but, some scientist guy bred a chicken with teeth by reverse genetic engineering... um, genetic engineering evolution in the reverse?... umm.... I whatever you call it for back breeding dormant traits into a species.
Also, pigs fly, in airplanes with humans sometimes.
though I've never seen a fish climb a tree, I've seen pictures of fish in trees after a rain storm.
mudskippers climb trees..kinda if jumping to a low branch on a mangrove counts
"The mule's offspring is half sibling"
BIG WHEELS KEEP ON TURNIN!
Actually, Mules CAN have babies, and not just because of discarding the father's genes. It's just extremely rare for a mule to foal at all, let alone without discarding the father's genes. It helps to consider that if you shuffle two decks together there's always a chance of drawing a non-repeating deck. We know this is the case because modern humans have a small number of genes from other non-human species such as neanderthals. If they just discarded the genes of the father it wouldn't have been possible for the genes to cross the species barrier. Despite being difficult, occasionally the hybrids would be able to breed with each other or humans. Due to the fact that there were more humans, and that it is apparently more likely to successfully breed a hybrid with a human than another hybrid, this explains why the genes became part of the common gene pool for all of humanity.
To be more specific, only one mule family was genetically tested in 2007 and only because the mule gave birth to a foal not once, but twice - so akin to lightning striking twice. In that case, in that case only, it was determined to be due to “hemiclonal transmission" - or the mare ignoring the male's genes as if they didn't exist. This is the only case this has ever been observed in mammals - in just a single individual - so it's very much premature to assume it applies to all cases, just that it's a better explanation in cases of repeated births.
Also, Chickens do have the genes for alligator teeth and sometimes are conceived with them through an Atavism, but because Chickens lost the gene required to break out of the eggs with teeth they all die when it occurs, but it's technically only one mutation away from having teeth.
and there are fish that fly and skip on mud, so while I've never seen one climb a tree it wouldn't be impossible and might be a good place for a fish to build a nest of clay if evolutionary pressure pushes it that way.
The only real impossibility would seem to be the flying pigs, because they would need wings and adapted bone structure.
What about "when the cat grows horns"
Or when a dog doesn’t lick you
What about pigs with an airline ticket ?
this really hit home it seems..
We discarded my father's jeans when they got old. Now morons buy them that way.
0:33 lol in iraq we say ‘on the month with no Friday’
My grandma always tells that to me
When I went to Brazil for holiday I heard "when sea water is sweet"
Pigs do fly when we transport livestock on airplanes, all terrestrial vertebrates are technically fish, and the ancestors of chickens had teeth. (French people also say "when chickens have teeth")
I wonder if the Nigerians got it from the French or the other way around?
I never knew that mules were a mix of a horse and a donkey. I thought mule was just another word referring to a donkey. I always heard the idiom, "stubborn as a mule." And thought it referred to just a donkey. Very cool to learn.
This video was so informative !!
Never taught this in reproductive systems chapter from our biology class.
Well, if it makes you feel any better, I majored in biology in college and I don’t recall ever learning about this in genetics. Of course the teacher was awful so I didn’t learn much of anything from genetics. Good thing I didn’t want to be a geneticist!
Wait mules can't have babies AM I THE ONLY ONE WHO DIDINT KNOW THIS
Not really, though I am curious about jennies.
A jenny is a female donkey. (Jacks and Jennies). Horses are stallions and mares.
A cross between a jackass and a mare is a mule, while a stallion and a jenny is a hinny.
My friend didn't know this... He learned this fact for the first time today...
Yes. You were the only one
Nope

If you chase a pig off a cliff it will fly for a moment. Or so I'm told.

"when pigs fly"
*mc ultimate flashbacks*
0:30 In Albania we say "When the donkey flies"
you guys are another level hh
Do you also say:"when pigs foal" ?
0:37 all of these have happened surprisingly! Mules very very rarely have foals, the occasional tornado or human intervention can cause pigs to ‘fly’, all amniotes are descended from fish so a monkey is technically a tree climbing fish, and many birds had teeth in the Cretaceous!
Me: If mules can’t have babies then how are there made?
My brain: Maybe they evolved
Mules:Yep that’s right
1. evolution isn't real
2. the video explained that they're made from a donkey and a horse, but aren't even technically a species because its a hybrid.
dang, im in Canada and i always hear and say "When the queen dies" 😂 gonna have to stop saying it if it ever happens but, lord knows that ladys gonna out live even me
You guys really use that 😂😂... British people will get mad
@@Lord_Alhaitham ah well, poor them? idk 🤣 its just a saying, like "when pigs fly"

Chickens actually have teeth, but due to epigenetic factors, they are shrunken down to a minuscule size where they are fused together and thus become unnoticeable.
I'm Turkish and I've never heard of fish climb trees saying in my life
Indeed. Not accurate at all. We have David Goldenberg (Script Writer) & Emily Elert (Script Editor) to blame for that one I guess. :)
Never heard of it too but "untill the donkey returns from water" might be more accurate ^^
"Balık kavağa çıkınca." which I've never heard of before either.

I've never heard the phrase either. But I'm not Turkish.
The reason the pet cloning industry failed is not only because it's super expensive but more importantly the animals were different. Humans can only clone an animals appearance, but it will never be possible to clone an animals soul. So to answer the q at the end, no, your cloned cat would not be the same as Yardley. It would look similar (even then with a variation or two such as a white hair that your old cat didn't have) but it would 100% behave differently. If your cat always made a cute noise and sat by the radiator, the new cat could be silent and choose to sit on the window sill etc. Yardley may have been peaceful, new cat might be crazy behaving. Add to that, the ill health and shorter life span of cloned animals. Yep it failed, and thank goodness! Humans already do incredibly negative things to animals. Human selective breeding of animals have created animals worldwide that suffer needlessly with health issues etc. Criminal, really.
The chicken having teeth is actually a french expression.
it's not uncommon for different countires/ cultures to use similar expressions... I learned that when i studied chinese as a second language

Grolar bears are the offspring of grizzlies and polar bears. We'll probably see more and more of them as those animals' ranges overlap more and more.
Alright i'll shut up now

They meet in Canada, when grizzlies go further north than usual, and polar bears further south. Melting ice is forcing polar bears south.
