Meiosis.

Offspring have half their mom's traits, half their dad's traits.

The male produces the sperm, and the female produces the egg.

Offspring have half of each of their parent's traits because of the process of mitosis.

Mitosis and Meiosis are similar.

All of your cells have 46 chromosomes.

Meiosis is like Mitosis, except twice.

The first stage of Meiosis is Prophase 1.

You and your brother would normally be different, except if you were identical twins.

Identical Twins! Shout out in the comments!

There are lots of stages in Meiosis, like Metaphase 1 and Telophase 1.

Meiosis marks a checkpoint between it with Cytokinesis.

There are more stages in Meiosis, including Prophase 2, Metaphase 2, Telophase 2, you get the point, don't you?

Finally, Meiosis finishes with another stage of Cytokinesis.

Half of your sperm( Of course, if you're a man) is female, half is male.

When (You know) happens, the sperm go into a crazy race to get to the egg.

The most common reproduction is sexual reproduction.

Sexual reproduction begins with sex cells.

We all have different sex cells.

The answer to the mystery of sexual reproduction is Meiosis.

Once again, there are so many reasons that you can't clone yourself.

If you took all the DNA from one of your parents, you would be a clone of them.

There are special cells that have only 23 cells, the sperm and the egg.

A special diploid cell splits in half two times in the process of Meiosis.

Part 1 and Part 2 of Meiosis are extremely similar in many ways.

Men produce sperm and women produce eggs after puberty begins.

If you want to know a good way to describe Meiosis, think of it as Mitosis, two times.

In the process of mitosis, the cells split into two cells with 46 chromosomes, but when those two cells split again, they become four cells, each with 23 chromosomes.

The vast majority of your cells can clone themselves.

If half of your cells were from your mom and half from your dad, you would look really weird.

Sperm and Egg cells are Haploid Cells.

All the stages of meiosis happen in mitosis too.

Each double chromosome has two chromatids.

In Meiosis, every copy is very, very different.

Double chromosomes trade their genetic codes in a process called recombination.

One of the pillars of natural selection is variation, so to speak.

Male cells have XY chromosomes, Female cells have XX chromosomes.

You need a Y chromosome to become a male.

Telophase 1 is the final stage of the first part of Meiosis.

After the first part of Meiosis, we have 2 haploid cells.

Next, in the second part of Meiosis, we will have 4 haploid cells, 2 male and 2 female.

All of the haploid cells produced in Meiosis are the same size, but they are going to be different in lots of ways.

Every human started as one tiny tiny cell.

Homologous means two cells have the same relation.

The egg is created when another cell splits into 4 but only 1 is used, the egg of course.

The other 3 cells are called Polar Bodies, and they are completely useless.

The first stage of Mitosis And Meiosis is Interphase.

In Prophase 1, the copies of the chromosomes stick to each other.

Your mother's chromosome' and your father's chromosomes' Xs get tangled up during Meiosis. All 4 chromatids will be different in lots of ways.

The 23rd pair of chromosomes will become part of your sex cells.

In Telophase 1, the nucleus duplicates itself.

In Cytokinesis, the cell completely duplicates itself.

Don't forget, Cytokinesis happens twice.

Prophase 2 is slightly different from Prophase 1.

At first, the egg in Meiosis splits into 1 egg and 1 polar body, after that, the egg splits into 1 egg and 1 polar body and the polar body splits into 2 polar bodies.

Lots of our sex cells are different.

Meiosis is also used by plants and animals which don't have live birth.

All of your body cells contain the same mix of DNA.

Only some cells can go through the process of mitosis.

Your sex cells are contained in your ovaries, if you are a woman, or your testes, if you are a man.

You were born to make life.

Men and women have to be a certain age before their sex cells are ready, there is a name for that stage of life, puberty, duh.

1 pair of your chromosomes will become your sex chromosomes.

You always end up with 4 cells in meiosis, but when you're a girl, the other 3 cells are useless, as you only need 1 egg.

It is amazing that you came from 1 cell. If you aren't surprised by this I don't know how to impress you.
