That's the egg, and we all know how this story goes.

Sperm

Fuck.

Tentura?

Cross...

Cross.

And it's now ready to essentially turn into an organism.

For my friend Christopher Cross in recognition of 25 years of loyalty of J.J. Hogarth, 1899 1934.

So we start with a zygote. This is a fertilized egg.

Just as an aside, this unification, this fertilization that occurred from this sperm cell to this egg cell, so it essentially penetrates into this egg cell and it creates this zygote, which is a fertilized egg cell from my mother, and this contains all DNA from both my father and my mother.

So this very first cell that was created from this fertilized egg, this is called a zygote.

So that very first cell that was essentially my mom's egg fertilized by a sperm cell from my father, that was a zygote, and as soon as it's successfully fertilized, it has 2N, or it has the diploid number of chromosomes in the case of humans, which I believe I am one of them.

Men, through their penis, they fertilize the eggs by the sperm coming out.

This is the gentleman...

And it's really an odd sort of structure.

We're visited by Dr, Dervaux. a psychiatrist,

That won't be enough. He's suffering from severe mental fatigue.

Let me do that Y chromosome in a separate color.

My father's sperm somehow met my mother's egg, and they fused.

That if Cross paints?

Hello, Mister Cross.

This is Noah Cross, if you don't know...

Clerk at Vauxhall Cross.

I feel like i'm going clinically insane.

How do they call him her their friends? Chris.

Making overtimes, Mister Cross?

Until soon, Mister Cross.

I had an artificial insemination with sperm from my husband.

And I said, Yeah.

Baby's first division

Of course, that's better than side meat.

Charmed, Mister Cross.

Noah Cross is your father, isn't he?

Are you getting any crosschatter?

I had an artificial insemination by donor.

I had a mental blow at that time.

And this is where the system gets really interesting.

But now with some of this vocabulary thrown out of the way, let's talk a little bit about zygotes and how do zygotes turn into people, and then how do those people essentially produce gametes, which then can fertilize other people's gametes to form more zygotes.

The focus of this video is how this fertilized egg develops once it has become a zygote.

I mean, he's gonna get another lecture, make another visit to the head shrinker.

They produce these gametes.

Some kind of psychological shock

female eggs were to be fertilized in a lab and given a cocktail of growth hormones.

So I have to get myself in the zone. Right. It's a bit of a cross of my arm.
