Meiosis

Question 1

What is meiosis?

Answer 1

Usually produces 4 daughter cells each with half the number of chromosomes as the parent cell

Question 2

When does meiosis occur?

Answer 2

I’m most animals meiosis occurs in the formation of gametes

Question 3

What happens during meiosis?

Answer 3

Homologous pairs of chromosomes separate so that the only one chromosome from each pair enters a daughter cell (haploid cell)

Question 4

What’s the process of meiosis?

Answer 4

The first division: homologous chromosomes pair up and their chromatids wrap around each other, equivalent portions of these chromatids may be exchanged in a process called crossing over. By the end of the division the homologous pairs have separated with one chromosome from each pair going into 2 daughter cells.
The second meiotic division: the chromatids move apart. At the end 4 cells have usually have been formed
