Question

Quizplus · Accepted Answer

Both sperm and eggs are haploid meaning that they have one set of DNA; one half of the amount that the fertilized egg will contain. In the testes four sperm are produced for each spermatogonium that begins spermatogenesis while in ovaries only one egg is produced for each folicle that begins oogenesis. Sperm have a flagella which moves it through the uterus and into the oviduct where the egg is located. The egg is moved to this location by cilia lining the oviduct along with muscular contractions. Sperm contribute only their DNA to the embryo while the egg contributes both DNA and the cytoplasmic components necessary for the cell to function.
