Meiosis in Sperm and Oocytes
Depicted below is meiosis during Human Spermatogenesis (on the left) and Human Oogenesis (on the right). In both germ cell lineages, the cells are undergoing the meiotic reductive divisions from the Diploid state (2N) to the Haploid state (1N). At the end of the two meiotic divisions, there are 4 haploid sperm produced, but only 1 haploid fertilizable egg.
