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

This would be sperm.

So that's a gamete and this is a gamete.

It's not just any cell in the body.

Oeufs. Un oeuf, des oeufs.

In the immortal germ line of human beings that is, the eggs that sit in the ovaries they actually sit there in a state of suspended animation for up to 50 years in the life of each woman.

And I'll draw the sperm much larger than it is normally relatively to the egg.

Where we left off after the meiosis videos is that we had two gametes.

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.

In some cases, another species like the North American Leopard Frog showed that males exposed to atrazine grew eggs in their testes.

Let me draw the sperm.

When I was a lad I ate four dozen eggs Every morning to help me get large

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.

Hey, listen. I, I got a big problem. I totally just lied to Pink.

Eggs?

Let me do that Y chromosome in a separate color.

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

In the case of a female, these would be ova, sperm or ova, and these are the gametes.

No, strawberries.

Want some eggs?

Uh, the eggs?

An egg!

I smell eggs.

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

A pair of X's gives us a girl, and an X and a Y together gives us a boy.

Oh. Egg rolls?

Sperm

Or look at it another way Suppose you have a dozen eggs.

It's turning the eggs.

Eggs.

Like a hardboiled egg.

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.

Meet the hermaphrodites.

And this is where the system gets really interesting.

And these buttons there those are chicken eggs.

Seung Jo and Eun Jo's lunches.

From Conception to Birth Oocyte

More eggs?

Eggies!

Milk and eggs.

Eggs. Powdered, but but I do 'em good.

And the germ cells, we've learned already, these are the ones that produce gametes.

I'm collecting from.

I think we have found the problem. Your ovarian follicles are still immature.

Even though she's allergic, I gave an egg to the child.
