46

17
Q

Where does meiosis take place?

A

Reproduction organs

18
Q

What is produced by meiosis?

A

Sex cells (gametes) humans egg cells and sperm cells

19
Q

What is the first stage of meiosis and why?

A

Mitosis because it allows the cells to replicate.

20
Q

What happens after the mitosis stage?

A

The cells divide to form gametes.
