@getyourglit2gether: You’re a genetic mosaic. 🎨 Is that not the coolest f**king thing?? I think that’s the coolest thing in the world. We will do female cascade next, there will be knowledge gaps, be patient. We are literally still catching up on female information… #anatomy #development #learnontiktok #womenshealth
So science just proved that gender is.. nonbinary?

Sooooo women even have to multitask and reorganize all the way down to a cellular level?

it’s not deactivated randomly. our cells decide which X has the most useful genes for their specific function. it’s like a genetic super power

I mean, are we surprised women’s biology wasn’t studied more thoroughly? This is fascinating!

“Nobody cares but it’s really cool” is a sentence every scientist on earth has muttered at one point or another 😂😂😂

I wonder how long some scientists actually have known or suspected this but rejected it because of their male bias.

We didn’t investigate something only about women??? Whaaaaaaaaaaaaaat

this is partly why tortoise/calico cats are multicolored! which is fun. and why it's rarer for boy cats since they only usually have one X not two+

Wow almost like nothing about biology is “basic” at all.

Sophie :
does that mean that females have less genetic material in each of our cells than males because we have to inactivate half of the genetics whereas males still have that little amount of Y in their cells?

Not me saying "isn't this mosaicism" then you say we are MOSAICs. MIND BLOWN

Omg I literally have toes from my dad on my right side and toes from my mom on my left side and was never able to figure out how that could be possible. Genes just in there rolling dice 🤯

Hehe Hoohoo :
Yeah this is why calico cats are the way that they are. Calicos are strictly female unless they’re XXY, because the black and orange are located on the two X chromosomes. But because of the barr bodies and the way that the cells split for mitosis, it’s a coin flip for which color it’ll be to duplicate. Thus you get patches of each mosaic cell :p

i’m an XX SRY+ male. i experienced normal male development with the exception of being sterile. when i did my genetic testing they determined i had cellular mosaicism - in roughly 50% of my cells, the maternal X is turned off and the paternal X (carrying the SRY gene) is active. In the other 50% of the cells, the paternal X is turned off and the maternal X is active

When I took Introduction to Genetics and learned about random X-chromosome inactivation *lyonization* and how it results in genetic mosaicism, my mind was BLOWN!!! 🤯😂 But what really made me laugh was learning about the SRY gene on the Y chromosome and its role in initiating male sex differentiation. I couldn’t get over the fact that the gene responsible for initiating male development is literally called “SRY.” All I could think was that the Y chromosome was apologizing for making someone a man. AHAHAHA! 😭😂
