Why Females Are Stripey

Each of us is made of a mixed-up jumble of cells. Most of you is you, but a few of your cells actually belong to your mom, stowaways that she left in your body.

But thanks to our sex chromosomes, it’s females who are the real mosaics. In this video from Veritasium, you’ll learn how biological females are like calico cats. Early in a female’s life, way back when her embryonic body was little more than a ball of cells just beginning to fold into basic patterns, a molecular coin was flipped inside each of her nuclei, and one of the two X chromosomes was silenced forever.

Why is this? Although our sex chromosomes are tiny compared to the other 44, they contain vital genes. But just like a genetic knockout can cause problems, so can too much of a gene product. Each cell in a female nucleus only expresses the genes on one of the two X chromosomes, muting the other so that the "dose" of X genes is pretty much the same between XY and XX individuals. 

Heads or tails, that epigenetic pattern persists for life, and although we can’t see them … women have “stripes”!

can we talk about how this fucking pbs show aimed at little kids easily talked about how anxiety is stressful but normal

Ok no but can we talk about this entire episode? 

It was called April 9th, and it was actually a response to the 9/11 attacks. It didn’t talk about the attacks themselves, but rather focused on teaching kids to deal with the all of the emotions that they might be feeling as a result. They set up a situation that might evoke similar emotions in children: a massive fire at the school.

Arthur’s dad was in the fire, so (as you can see above), Arthur is constantly worried about his dad’s safety.

Sue Ellen is grieving because her journal, which contained a huge amount of precious memories, was destroyed in the fire. Muffy is confused why she can’t just cheer Sue Ellen up by giving her a new journal.

Buster wasn’t at school that day, and feels confused and guilty that he isn’t sad about the fire like the other kids. He then befriends the school janitor, who has to retire due to an injury that, at his age, is pretty serious.

Binky actually saw the flames, and is constantly traumatized by the event. He doesn’t tell anyone because he feels like he would lose his tough-guy reputation if he admitted that he was scared.

The episode teaches kids that all of these emotions are perfectly normal and natural, that there’s not one right way to feel, and that even if it takes a while, things are going to be okay.

The thing that makes this show so great, in my opinion, is that it knows that kids are intellegent and strong enough to deal with these things if you present them in the right way. It doesn’t hide them, it doesn’t sugar coat them, it just presents them in a way that children can understand and shows them how to deal with them.

In general, PBS ( I think this show was on PBS) has always been very good at providing intelligent children’s programming that gives children a voice and explains all types of concepts in a way that children will understand. Kids don’t have a problem understanding things if it’s explained to them in a way they get, what they don’t have an easy time with is articulation, and this gives them a way to, much like Sesame Street, Mr Rogers, etc have always been able to.

I just love intelligent childrens programming so much.

I had a very angry conversation over comics and equality today and wanted to share it.
I am 24 years old, and Delilah is my service dog. Her job is to calm me down when I get extremely angry. But I make comics about our antics, and she brightens my day.
