Now that we’ve lightened the mood a bit, let’s talk about how it all begins. Recall from previous lessons that the gametes, sperm and egg, are haploid cells containing half of the chromosomes of a somatic cell. (If you are just joining us, all of these terms are defined in earlier classes here at Pro-Life Academy. As always, no chewing gum in class!)

During intercourse, the male ejaculates roughly 500,000,000 sperm cells. Only 50-500 cells reach the egg.
Fertilization
