Describe one function, brought about by the process of meiosis thatspermatogenesis and oogenesis have in common. Please write the similarities between spermatogenesis and oogenesis in a paragraph ratherthan a table. Please discuss the process mentioning differentiation, multiplication anddivision. How many stages of meiosis do they go through. Please mention if haploid ordiploid cells are formed.
The process of oogenesis is often described as theproduction of a haploid egg by meiosis, but in someanimals, including humans, this description is notentirely accurate. Explain.
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?
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.
The result of spermatogenesis is: 4 viable haploid spermatids. 1 viable haploid spermatid and 3 haploid polar bodies. 4 viable diploid spermatids. 1 viable diploid spermatids and 3 diploid polar bodies. Don't copy from Google
ARRANGE THE FOLLOWING EVENTS IN CORRECT SEQUENCE from 1-13: Penetration of the zona pellucida Cortical reaction 1st cleavage Acrosomal membranes rupture, and release their enzyme contents Penetration of the corona radiata Depolarization of egg membranes Migration of cortical cytoplasm to form gray crescent Sperm attach loosely on the zona pellucida Zona reaction Oocyte completes meiotic division ZP3 tenaciously binds acrosome-intact sperm Release of Ca+2 in egg cytoplasm from its bound state Amphimixis
Oogenesis in the female results in one functional gamete—the egg, or ovum. What other cells are produced? What is the significance of this rather wasteful type of gamete production—that is, production of a single functional gamete instead of four, as seen in males?
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?
There are 6 major events in fertilization. Discuss the process of fertilization or conception, with emphasis on the sperm-egg interaction. Proteins on the sperm plasma membrane bind to ZP3 molecules within the zona pellucida of the egg. Why is this event important? Zona binding triggers the acrosome reaction, in which the sperm plasma membrane fuses with the outer acrosomal membrane, causing exocytosis of acrosomal contents. What is in the "acrosomal content"? Acrosomal enzymes begin to dissolve a hole in the zona pellucida. This enzymatic degradation, accompanied by rapid sperm tail beating, moves the sperm through the zona. Where does the sperm intend to reach?
In the process of Oogenesis in animal cells, will the genotype of the second polar body (derived from meiosis II) always be identical to that of the ootid? Why or why not?
Which of the following is NOT correct about oogenesis? * O the oocyte undergoes meiosis to produce one egg cell and three polar bodies O the oocyte undergoes mitosis to produce female gametes ) it occurs only in females diploid cell undergoes meiosis to produce four haploid cells it includes asymmetric division during gametes formation OO OO
Polar bodies are generated during 1. Mitosis in females 2. Meiosis in males 3. Meiosis females 4. Meiosis in both females and males
