All of the cells in our body except for our sex cells have 46 chromosomes.

Our sex cells have 23. Why?

Answer: Because our sex cells (23) are the sperm and the egg. Copyright © 2010 Ryan P. Murphy

Answer: Because our sex cells (23) are the sperm and the egg. When sperm (23) and egg (23) meet, you get the correct number of human chromosomes of 46. Copyright © 2010 Ryan P. Murphy
