When a female embryo is four days old it consists of just 100 cells. At this point the x-chromosome from Mom and the one from Dad are both active. But in order for proper development to occur, one of the x chromosomes must be switched off.
Through a tiny molecular battle within each cell, one of the x-chromosomes wins and remains active while the loser is deactivated.
This is done by wrapping the DNA tighter around proteins, modifying histone tails, and DNA methylation - molecular markers to indicate this DNA should not be read.
What's surprising is that it's pretty random which x chromosome wins - sometimes it's Mom's and sometimes it's Dad's. So when a female is just 100 cells big, her cells have a mix of active x-chromosomes, some from Mom and some from Dad.

Awww....😂
@@sungibatman1996 wait that's a super interesting question
Not sure if you need some kind hormone to keep your heart pumping but do we need dna to process information in our mind at the first place?
igamse i dont know the human body much but dna is not required in braincells to think.. at least for the breif time you are alive
Leave DNA , Even your Intestines are much longer / taller than you
AHAH same mate we out here

I have a degree in genetic engineering. Your 5 minute presentation was the most concise explanation of histone packaging, X-inactivation and epigenetics I have ever seen.
I had a genetics professor that was so trash at teaching genetics that all 4 of his classes one semester were on course to fail the class. The highest grade was a mid C and that kid had a mental breakdown and left before the semester even ended. He sent an angry email to each student to call them lazy but the board made him change everyone’s grades in the end
Shows what happens when science gets a budget :)
@@HeyitsBri_ That's terrible. We had a Statistics class like that. We all know that Stats is hard at the best of times, except for math nerds, but this lecturer just couldn't teach it well. He was young and tried hard, but it just wasn't happening. The grades ended getting "adjusted" up...
people get so angry when you provide them with facts. we have to abandon science to protect the feelings of certain groups whom I cannot name
@@HeyitsBri_ That's horrible, if their job is to teach and everyone is failing then they suck at their job!
"Only female cats can be be calico cats"
My male calico cat with an extra chromosome: "Woof!"
I also had a male calico. 😊
It actually ticked me off that he said that like erm akchually 🤓
Yes male calicos are XXY :D thats why they still have two XX chromosomes
A pattern determines calico...not a picture you saw on Google or whatever always says it is. It's not just multiple colors
@@eclecticraeen How bold of you to assume we don’t have a clue what we’re talking about and that we Googled cat pics just to reply to a comment on TH-cam. Bless your little heart and thanks for sharing.

Damn... That would be a step closer to achieve catgirls
@@arne_mh if women were originally stripy, you wouldn't be dissapointed about it, because we humans would be used to it and would consider it normal the same way we consider our 5 fingers on our hand normal
Calicos must be non-binary, then, since they have three colours: one for male, one for female, and ...

Bruh it's not about stretch marks?
I thought it was about visible veins or something.
I'm a dude with stretch markd
Funny how RIGHT before the visualisation of the stripes being created by multiplying cells, my thought was, "This is all very interesting, but I wonder when it'll all come together so that the creation of stripes makes sense." That animation was an awesome visual learning device implemented at the exact right time, at least for me.
I'm also glad that you included the Calico bit in the end, because that's a bit of trivia I've been aware of for quite some time, but never really understood why or how it could be true. I'm now VERY curious about other animals with such colourations!

@@tijgo6 uh oh
Male cats actually can be calico they’re just very very rare. They have a specific mutation which leaves them with XXY chromosomes.
Cat Down syndrome basically?
Would that make them male or intersex?
@@SilverRyuu it would make them intersex
@@SilverRyuu intersex but its easier to just classify them as male calicos-- as that's literally what they are. just infertile.
It would be cool for you to do a piece on generational trauma and epigenetics. There's some excellent research out there on the subject.
I would love to learn more about that through this format. The explanation was so clear.
title: "why women are stripy"
me: *looks down in confusion and fear*
we be lookin like bacon
tasty
MMmmMmm
I too was confused, i was like wth is he talking about stretch marks or something men can have that too, glad i'm not the stripey one tho

*macaroni salad noises* 😭
@@bloomfire1998 Yup. The sounds are in the source material he used.
Last week I heard about X chromosome inactivation at a laboratory seminar. And now they are already recommending me a video from 9 years ago on how it works. Thank you!
As a pre-med student, this is an amazing way to explain codominant genes and cell differentiation in a simple, understandable manner. Codominant genes can be found in any chromosome pair but in the case of the sex-determining pair of chromosomes it can lead to alteration of the phenotypical percentages with a specific trait eg. Female Calico cat having black and white fur and a male cat of the same species having only one color fur since the male cat has only one allele for color expression in fur (its probably more than one but let's keep it simple) means that the genotypes for the trait body color are
X1 for black fur color
X2 for white fur color
Y chromosome doesn't carry any color alleles
so a female can be either X1X2, X1X1, X2X2 (black and white, black or white respectfully)
and a male can only be X1Y X2Y (black or white respectively)
great explanation, now I understand the video better
Thank you for explaining!
Next video: Why does all intra-cellular activity produce macaroni salad noises?
Mitochussy
Whaaaaaaaa…?
😳
Hypothesis: cells are made of macaroni salad
It's organic tearing noises.
So you're telling me that women are secretly zebras?
Yes
Yes. We must hide.
Umm, that's shebras tyvm! (snaps in a Z formation)
No, we’re all Calico Cats.
No, they’re actually 2001 Ford Ranger XLT’s
It’s cool that this older video popped up in the algorithm, and the Amarante music was a really nice surprise! I’m a big fan of them.
This was satisfyingly informative
Ty!!!
I can really feel how painful this was to animate
The protein animations were probably from some supercomputer tbh
A lot of it's a physics simulation.
The dna ight have been done justwith noise modifiers
it's probably done mainly with physics sim
To render. Oh god the rendering.
Who knew DNA was so noisy.
Right
Kj16V DNA, Lalalalalalaaa, LALALALALALAA
everything is noisy at that scale
wonder why is so rare to see this animation accuracy even today

Why does there have to be sound for the wiggly stuff
😭
Because they need a use for expired mayonnaise. All expired mayonnaise is used for sound effects. Stir a jar of mayo = worms, slimy monsters, bubbling swamps, and now DNA.

Lean up , yep I got spots from acne n mole's, scar's, they do fade a bit
Strach Marks stay they aint like acne scars.
I'm a man and because i was obese in my teens i'm full of them
@Lalogue They can be treated with laser removal, natural remedies, and face peels. Eventually, they would be so faint you couldn't really tell they are there. Also depends on how bad the scar is though.
@@lunareclipse- I was one of those early puberty kids at 8. I had all the stretch marks. They faded by 16 for me.

This was totally mind blowing!!
The cat's little "mrrp" made me so unreasonably happy

+Rudest Rickle Alive Actually, you would insert millions of sperm cells, most of which would die in a very short period of time. Any remaining sperm would have to survive to an egg that is either in the uterus or the fallopian tubes/oviducts. The two cells would merge to form a zygote, that would attach itself to the lining of the uterus. After cell division begins, after a period of a few weeks passes, the clump of cells can now be called an embryo; in a couple of months, it could be called a fetus. After the nine month human gestation period, the mother would give birth to the fetus, which can now be called an infant or baby, as it had just been born. Babies only are called babies after birth has taken place.
TL;DR : Putting a baby in a woman would not be sexual. It would just be very, very painful and disturbing.
Humans would need to have the skin-colour gene on the X-chromosome like the Calico cats.
Does anyone else just look down and suddenly realise "Oh, heck, I really exist, don't I?"
Yeaaasssss !
Ugh dont remind me

@@mendelian8768 why is brother written in quotation marks?
Now that I’ve taken a genetics class I can actually understand everything being said in this video. I remember watching this a few years ago and only kinda grasping the concept, but now it makes much more sense
This is amazing! Thank you! Are you able to expand on the natural variations of this? That is, can you include the variations that define intersex? For too long, biology education and popular understanding of binary (either male or female) sex biology and genetics has avoided the legimate, scientific and normal variation (maybe considered mutation in science, but that term in the wider popular community has far more pejorative connotations...) of sex genes. It's time we included variations as normal rather than aberrations of the most common instances of biology. Thanks, again! 🙏
the sound effects of the cells are disturbing

My daughter developed an allergic reaction on her skin and you could actually see those stripes! The university hospital was very interested to document this.
what allergy is it and is your daughter okay?
@@norachan30 all good and is quite some time ago. Thanks for asking! The likely cause was an infection due to an earring caused by an alergic reaction to the metal (nickel). Once she took off the earrings the infection healed and the symptoms went away very quickly. Take care!

Only one of her part is allergic?
Yoo that's actually really cool. Hopefully she's okay now though
@@cheeryberrie She is absolutely fine and it never occurred again. This was years ago and she is actually studying now to be come a med doctor herself.

I knew about the striping from DNA from different parents, but I didn't know why men *aren't* stripey. This video explained that for me.
So what I learned today, is that being born female made me a tiger. Nice.

Did the Foley artist use bong water noise for part of this?
I would be so interested to know how HRT affects all of this! If it does at all. This was fascinating and I think it’s so cool how we’ve mapped out this kind of stuff enough that we can have control over what our bodies look like from the outside. We can essentially hack our bodies now lmao it’s so neat
News flash, it doesn't😂 you think HRT would give you a new set of chromosomes?
Aside from mr. funny edgelord comment over mine, i don't think it does. HRT only affects our hormonal stuff and secondary characteristics, not DNA.
@@spike9535 makes sense! Yeah, I wasn’t sure if it would. So it would mean if humans did have stripes like cats trans men would also have them and trans women wouldn’t?

I’ve heard that quantum fluctuations from moments after the Big Bang were stretched out across space when inflation occurred. This is what resulted in the slightly bumpy texture of the Cosmic Microwave Background and the gravitational regions for galactic superclusters.
The banding from the initial 100 cells spread across the body reminded me of that for some reason.
They are called Blaschko lines and can be seen under consentrated uv light especially on the back

Man I am genuinely so disappointed to learn that I’m not actually stripy.. I was hoping after this video I would look closer and see stripes and go “woah, stripes!” This is so sad
i mean, stretch marks kinda show that strippy-ness, so if you have those, there you go XP
@@tavrosnitram1529 this is technically true but men have those too. If you get a magnifine glass and look at your skin it's quite stripey though too!
You technically do have them! They just, don't present themselves in any visible way, because we don't have a gene to cause a different color like that. But they do technically exist! They're just the same color as the rest of your skin.

if women are striped like tigers, why does everyone call my mom a cougar? ; -;
Did she used to drive a Mercury Cougar?
No, I think it's because she drives a Mercury Cougar. An adult female that engages in sexual congress with under age males is call a "defendant". (Pedophile, perv, child molestor, pedaster are also synonyms.) If your reference to 'sleep' is not somnambulation but sexual intercourse, then maybe we need to hotline her.
(BTW: Even think how stupid word 'sleep' is to refer to sex? If a partner is so boring, maybe.)

@@datnamedoh4877 they're genetically neither male nor female. They're XXY
@@datnamedoh4877 no. A hermaphrodite has both male and female reproductive organs. For example, a snail is a hermaphroditic species. Sometimes a non hermaphrodiric species can be born with bothe male and female reproductive organs (one set is almost always incomplete and nonfunctional)
An xxy individual (this is called kleinfelter syndrome) is still a male. It only has male reproductive organs and is usually sterile but not always. Male and female aren't as clear cut as people usually think.

There are male calicos but its super rare and only happens when the cat has a mutation having XXY

@@azmah8730 Now I am confused by why each X chromosome doesn't try to deactivate the other, leaving XXY individuals as males with different X chromosomes in each cell.
Strictly speaking, is it accurate to describe them as male if their sex chromosomes aren't XY? I genuinely am not sure
Rex the Royalist why wouldn't it be?
Bwizz245 | because biologically what defines your sex at conception is your sex chromosomes, so if its sex chromosomes aren't the male configuration of XY is the cat biologically male?
Males with an extra X chromosone are also stripey.

Nice to know women at least have tiger strips besides stretch marks!
Interesting.. So it sounds like if you cloned a Calico cat from a single cell, it would have totally different spots, or maybe no spots at all?
Different spots, yeah. If you just pulled out the genome, you'd still end up with two X-chromosomes, and the more-or-less random selection would still happen at the 100-cell stage. You wouldn't get no spots, unless you missed the bound-up one or something. Of course, then you'd only have one X chromosome, and you'd need to duplicate it to avoid genetic abnormalities.
