The appropriate size of the sperm compared to the egg is illustrated bythe two nonfertilizing sperm cells still attached to the zygote. Only one sperm enters the oocyte to fertilize itand the rest remain outside.Genetic information is carried in chromosomes.1. How many chromosomes are found in sperm and eggs?2.
