Most humans have 46 chromosomes (23 pairs) in their body cells.

Most humans have 46 chromosomes (23 pairs) in their body cells. They have only 23 chromsomes in their gametes. Why do you think gametes only have half the number of chromsomes?. Talk to the people around you about what a Punnett square is used for.
