Y chromosome

And the Dr. Sky experience continues, folks.

But what I'd like to do on the other side of the break is talk about what Dr. Drakes is talking about in a location in Pakistan called the Mohenjo-daro, and it has a lot to do with the whole concept of chromosomes and something called the Y chromosome.

Her research is incredible And we appreciate our special guest.

We'll be right back after these announcements.

Mm-hmm.

Mythology because I know it's talking about these people who are not quite, um, human beings, uh, or half human, half god.

And then science because of the fact, um, some, some scientists have looked at that particular story and said, "You know what? Somewhere along the line about 5 to 7,000 years ago, there was a bottleneck in the Y chromosome." Now, of course, um, we have 23 pairs, and one of those pairs is an X and a Y.

Correct.

But please explain this to this audience.

Mohenjo-Daro, what is it? Where is it, again? And what's the relationship between that and your study called the Y chromosome that we know in biology? This is interesting.

Okay.

Mohenjo-Daro is in the Indus Valley.

Mm-hmm.

Steven Prater- How the regulated these genes are turned on and off differences their differences in alternative splicing a gene will have exons introns these intervening.

regions these spacers are these introns and these will be spliced out to create numerous functional products there's differences in those alternative splicing epigenetic differences and one major difference here the human y chromosome so the y chromosome is paternally inherited passed down on one side the the father's side so looking at this visual here The human Y and the chimpanzee Y, the chimpanzee Y is half the size.

It's going to get a drink of water here.

When you consider overall architecture, size differences in gene content, they're less than 30% the same.

So the human Y and the gorilla Y are actually more similar to each other than either is to the chimpanzee Y.

How do you explain those differences? Notice this, right from the secular literature.

Despite a recent divergence of these species, their Y chromosomes differ enormously in size and gene content.

They point out the chimpanzee Y is only half the size of the human Y, and they were shocked.
