Q

What is Mitosis and what does it produce?

A

Mitosis produces two genetically identical daughter cells that are Diploids with 46 chromosomes. The purpose of Mitosis is to make more body cells.

Q

What is Meiosis and what does it produce?

A

Meiosis produces four genetically unique daughter cells that are haploids with 23 chromosomes. The purpose of Meiosis is to make gametes (sex cells)

17
Q

How many times does Mitosis go through PMAT?

A

Mitosis goes through PMAT once

18
Q

How many times does Meiosis go through PMAT?

A

Meiosis goes through PMAT twice.

19
Q

What is the significance of Meiosis to sexual reproduction?

A

It increases genetic variations, increases new combination of genes, reduces the number of chromosomes to make haploid gametes, and creates genetically unique offspring
