Question

- How many chromosomes do human sex cells have? Why?- How many cell divisions must take place to obtain the correct number of chromosomes in each sex cell?

Answer 1

1. There are 23 unpaired chromosomes in each sex cell.

Step-by-step explanation:

This is because our chromosomes exist in matching pairs with one chromosome of each pair being inherited from each biological parent. So, when the male and female sex cells are combined it produces 46 chromosomes for the child.

2. Two meiotic divisions.

Step-by-step explanation:

Meiosis I and meiosis II, are required to produce gametes. It produces four cells containing half the original amount of genetic information.
