Gametes have half the usual number of chromosomes |
-during sexual reproduction, 2 cells called gametes combine to form a new individual -gametes only have one copy of each chromosome. This is so that you can combine one sex cell from the mother and one sex cell from the father and still end up with the right number of chromosomes in body cells. Human body cells have 46 chromosomes. The gametes have 23 chromosomes each, when an egg and sperm combine, you get 46 chromosomes |
