Cell Biology Different Types Of Spermatogenesis, Oogenesis, and Fertilization
The current models presented in Figure 3 served because the foundation for developing brand new theory models.
Spermatogenesis ( Figure 3A ): Spermatocytes produce 4 spermatids, 2 of which may have X intercourse chromosome therefore the other 2 spermatids have Y intercourse chromosome. Just 2 associated with 4 spermatids take part in genetic recombination during meiosis we.
Oogenesis ( Figure 3B ): since the 4 gametes aren’t differentiated, the assumption is that any 2 gametes can develop the oocyte that is secondary within an ovum with only 1 X chromosome. Continue reading
