20 chromosomes

Explanation:

A sex cell is a haploid cell. That is a sex cell like an egg has only half the chromosomes of a normal cell. This is because the sex cell of the female ( egg) must combine with the sex cell of the male ( sperm)

to form the fertilized egg or embryo which is the beginning of a new life, or organism. This newly formed cell with twice the chromosomes of a sex cell then undergoes mitosis to duplicate itself until there are enough cells with identical DNA toani form the complete organism.
