Why Can't Mules Have Babies?

- เผยแพร่เมื่อ 22 ส.ค. 2016
- Hybrid animals are infertile because of the way their sex cells form. But sometimes, life finds a way.
FYI: We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some handy keywords to get your googling started:
- Hybrid organisms: The offspring of two animals or plants of different breeds, varieties, species or genera.
- Mitosis: A process of cell division that produces copies of the original cell.
- Meiosis: A process of cell dividion that produces new daughter cells with half the chromosome number of the original cell.
- Sex cell, or gamete: a cell that fuses with another cell during fertilization (conception) in organisms that sexually reproduce.
- Hemiclonal transmission: The rare occurence in which only maternal DNA gets passed along during the creation of sex cells.
Species featured in this video:
- Mule, is the offspring of a male donkey (jack) and a female horse (mare)
- Liger, is a hybrid cross between a male lion (Panthera leo) and a female tiger (Panthera tigris)
- Zonkey, is the offspring of a zebra and a donkey. Zebra hybrids are generally known as zebroids
- Beefalo, also known as cattalo, is the offspring of a domestic cattle (Bos taurus) and an American buffalo (Bison bison)
- Cama, is the offspring of a male dromedary camel and a female llama.

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...

Yeah when you finally find an interest in the subject and you ask into it you get dismissed, told that you shouldn't waste your time on it cause it wont be in your test.
Thank you educational system for stopping my desire to engage in an academic subject.
You just have really crappy teachers then, each wednesday we had discussions on the subject, but actually, they always drifted off into other subjects.
it's incomplete example, bcz they explain why two spices can't cross, but don't explain why horse + donkey is OK (though result is sterile offspring).
Just because they didn't show the information in your head with a silver platter, doesn't mean they didn't teach this at school. Stop trying to be edgy you 13 year old and go and learn in school.

Yea yea real story
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.
Thanks for this very interesting information. I really enjoyed reading it! :-)
when it does give birth is it a baby mule or a baby donkey or horse?
THANK YOU FOR EXPLAINING THIS! I have been googling all morning long for a short, clear-cut answer lol
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.
yeah, there's lots of hypotheses about hybrid male sterility. this video, i think, focuses on one (the Dominance Hypothesis for Haldane's Rule).

Geese: 👁👁
Also there was that chicken that was genetically modified to grow reptile teeth or something
@@Cheesepuff8 yikes
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.
I need to point out that geneticists actually activated chicken-teeth at one point.
True so Nigerians are gonna have to change they're saying when chickensaurus rises
That might happen...
also two people made roosterteeth

So... if a female mule were to produce a foal with a horse, it would end up being a horse?
Hi KvaGram! Very clever - and the answer is likely yes, although we don't have documented proof that that has happened.
How has that not happened yet? And if it has why wasn't it documented? Q.Q
I don't think I'm going to the gym today and I'm still not sure what the actual number one in a while ago but the fact is a good time with the new version is better to be the first half of the day after a long day at the same thing to say it is not the same thing to say it is not the same time and it was the best of the day after a long day at the same time and it was the best of the best way of the best thing to say that you are the only thing is a good time with the best thing to say it to be the same thing as the first half of the day before my eyes
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.
Well when you apologize to my mule , like I know you are going to,see he gets this crazy idea you was laughing at him😂

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?
Such a great alternative to 'first'
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
they are hybrids within a species not with a other species.
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.
Dingoes are classed as separate to dogs but they breed with domestic dogs all the time.
That's incorrect. Their genus is the same but the species is not.

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

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.
"When pigs fly" is a achevement in Minecraft when you ride a pig down a 5 block deep cliff.
Thank u for making this vid for letting everyone know!u have a new sub!make more vids!!
Me: Pssh... pigs can fly! *hangs pig high up*
Everyone- *water sheep flashbacks*
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.
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.
Me either. Bende ilk defa duyuyorum o sözü 😀
I've never heard the phrase either. But I'm not Turkish.
In Somalia we say "when this palm grows hair 🖐🏽" 😂
That's from too much masturbation...
Pretty sure we don't have hairy palm
@@jugoojaman7940
Exactly. Saying that is the Somali equivalent of "When pigs fly" and "when hell freezes over". It just means that whatever it is that you're suggesting is impossible.
“Hybrid animals very rarely make babies of their own”
Wolfdogs: *Are we a joke to you?!*
Rarely!!! Dha!!!
As someone who’s grown up around Savannah’s (a hybrid cat, a cross between African servals and domestic house cats) being bred, I’m a tad confused now lol. I know high generation (over f5) male Savannah’s can’t really reproduce but female Savannah’s have no problem reproducing with a male Savannah as the stud, no matter what generation the female is. Genetics are truly fascinating!
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
"When Fish's fly"
Me literally confusion rn
very informative video
I thought "when the mule foals" was more akin to "once in a blue moon."
