wants to confirm one thing, will germ cell really undergoes the mitosis? Isn't the germ cell fuse with another germ cell to form the first cell and then undergoes the mitosis. So in such case the first cell should be somatic cell.
guan yilin I think you are confusing the germ cell with the gamete. Two gametes fuse to form a zygote, which undergoes mitosis and develops into a foetus. On the other hand, an example of a germ cell is spermatogonium. Spermatogonia can undergo mitosis or meiosis. If a spermatogonium undergoes, meiosis, it will form 4 sperms. However, some spertmatogonia undergo mitosis to produce more spermatogonia so that a person never runs out of spermatogonia.
