Chase and Christina were studying for their last anatomy and physiology exam of the semester. After reviewing his notes on meiosis, Chase said, "Well, since meiosis is the same in males and females, I don't need to study the meiosis notes from the female reproductive system lecture." Christina quickly pointed out that he was wrong and that if he reviewed his notes he would see that meiosis was very different in males and females. With some information from previous chapters and after reading chapter 28, explain the major differences between meiosis in males and females. Q1 Explain the differences between meiosis in males and females.

Q4 Compare and contrast clinical age and postovulatory age for fertilization, implantation, beginning of fetal period and parturition.
