We get unbelievable segregation.

The Supreme Court attacks school segregation.

They're both chromosome 3.

That's my Y chromosome.

The masses are entirely ignorant of the segregation problem.

I don't agree with segregation of people by race.

Ruby Bridges helped to end segregation in the United States.

It's on the X chromosome.

Then you get a chromosome.

So let's say we look at chromosome number I'll just call this chromosome number 3.

The chromosome is literally blown apart.

So this is a single chromosome.

Now, let's call this chromosome 3.

So this guy has pulled one copy of that chromosome and one copy of this chromosome.

The chromosome that was in the cell doesn't have one the chromosome we put in does.

The new chromosome went into the cell.

look, this has my full chromosome complement.

The first point to be discussed is whether segregation existed in this district.

And in the other case, the sperm is carrying an X chromosome, meeting the X chromosome of the egg.

Let me draw this whole purple chromosome there.

let's say it has this chromosome right here.

It's there for them the Y chromosome prize.

So maybe for this chromosome I get it from my dad, from the next chromosome, I get it from my mom.

This huge package of DNA is called a chromosome.

Each tiny mass of DNA is called a chromosome.

And then they have this longer purple chromosome here.

So let me zoom in on chromosome number 3.

We have 23 pairs of chromosomes, and in each pair, we have one chromosome from our mother and one chromosome from our father.

And you have two strands of DNA in each chromosome.

And if we do, can we boot up a chromosome?

Let me do that Y chromosome in a separate color.

Chromosome one top left, bottom right are the sex chromosomes.

The significant point as regards the segregation problem is to clarify the value system of each group.

This chromosome 3, maybe it contains this trait for hair color.

So someplace on this chromosome, there's a gene for hair straightness.

And that era of terrorism, of course, was followed by segregation and decades of racial subordination and apartheid.

And in this scenario, I want to imagine that, in one case, the sperm is carrying a Y chromosome, meeting that X chromosome of the egg.

Even though we have two chromatids, one for each chromosome, now we have four chromatids, two for each chromosome, we still say we only have two chromosomes.

The book of you would have 46 chapters, one for each chromosome.

It had two pairs of homologous chromosome, but it had four chromosomes.

Remember, chromosome is just a big if you take the DNA, the

So let me say it has this chromosome right here and then

It got expressed and it recognized the other chromosome as foreign material, chewed it up, and so we ended up just with a cell with the new chromosome.

When the cell feels it's ready to go, it rips apart the chromosome.

And so we started down the road of can we synthesize a chromosome?
