Document Summary

Spermatogenesis: process of turning sperm gamete into sperm cell. Oogenesis: process of making an egg from an egg gamete cell. Haploid from meiosis goes through spermatogenesis and gets larger to make sperm. Results in a mature sperm with less cytoplasm and long flagellum. Spermatogenesis takes place throughout a man"s life and during mating seasons every year. Divided towards primary oocyte and other to polar body. After meiosis 2, only 1 cell survives, purpose is to give it enough nutrients and cytoplasm. In humans, meiosis 1 begins before birth in ovarian tissues, and eggs are frozen. Menopause: the pause of the frozen eggs prior birth till fertilization. Shows all the chromosomes in a cell arranged in a grid from largest to smallest with centromeres lined up. Chromosomes are stained with giemsa, a chemical that makes a and t bonds. Amniocentesis: insert a syringe in amniotic fluid to take floating skin cells.
