Solved in 2 steps
- What structural and biochemical changes does the spermatid undergo during permiogenesis?How do these changes help the future gamete in performing its role in fertilization?How does the structural and biochemical changes during spermiogenesis help the sperm in fertilization?What are two important differences between the processes of spermatogenesis and oogenesis in animals?
- Describe the development of an oocyte from primordial follicle to when it is released at ovulation. How do hormones contribute to this progression? Describe the development of a spermatogonia to a spermatozoa. How do hormones contribute to this progression? What is the function of Sertoli and Leydig cells?In humans, gametogenesis in both sexes relies on meiosis. However, spermatogenesis produces four gametes while oogenesis produces only one. Explain why this is so, including the specific structures or processes involved.Why is it important for the sperm in internally fertilizing animals to undergo acrosome reaction at the right time?
- What means to retain the ability to become any cell type—including germ-line cells and gametes—when exposed to the appropriate signals in a developing embryo?If one follows 50 primary oocytes in an animal through theirvarious stages of oogenesis, how many secondary oocytes wouldbe formed? How many first polar bodies would be formed? Howmany ootids would be formed? If one follows 50 primary spermatocytes in an animal through their various stages of spermatogenesis, how many secondary spermatocytes would beformed? How many spermatids would be formed?How is the polar body formed in a way that the oocyte retains most of the cytoplasm? And how do thegamete recognition proteins interact with cell fusion proteins to allow the sperm to enter the egg?
- What is the differences between Mammals and Frogs in Spermatogenesis?In a possible future scenario, male fertility drops to zero, but, luckily, scientists develop a way for women to pro-duce babies by virgin birth. Meiocytes are converted di-rectly (without undergoing meiosis) into zygotes, which implant in the usual way. What would be the short- andlong-term effects in such a society?A female egg cell has two outer membranes how does the egg cell prevent polyspermy? if polyspermy happens, will the fertilization be viable?
