- Oogenesis is the process of female gamete (ovum or egg) production in animals. Spermatogenesis is the process of male gamete (sperm) production in animals. Provide two major differences between the processes of oogenesis and spermatogenesis. Provide one similarity between the processes of oogenesis and spermatogenesis.arrow_forwardWhat is the most significant difference in the process of gametogenesis comparing oogenesis with spermatogenesis?arrow_forwardIn human spermatogenesis, mitosis of a stem cell gives rise to one cell that remains a stem cell and one cell that becomes a spermatogonium. (a) Draw four rounds of mitosis for a stem cell, and label the daughter cells. (b) For one spermatogonium, draw the cells it would produce from one round of mitosis followed by meiosis. Label the cells, and label mitosis and meiosis. (c) Explain what would happen if stem cells divided like spermatogonia.arrow_forward
- Draw a schematic diagram showing spermatogenesis vis-à-vis oogenesis. Label the stage of development and chromosome number of daughter cells at the following levels of maturation: (a) mitotic proliferation (b) meiosis I and II (c) maturation.

- Fertilization is the fusion of haploid gametes, ovum and spermatozoon, to form a diploid zygote.

How are they different?arrow_forward
- In-vitro fertilization occurs in the laboratory. The resulting embryos remain in a laboratory culture for up to six days before being transferred to the potential mother. If fertilization had occurred naturally (i.e., inside the female reproductive system instead of in-vitro), where would the embryo be and what developmental processes would it be undergoing during those first six days of development?arrow_forwardWhat is the number of chromosomes in the following cells? Primary oocyte,secondary oocyte, ootid and follicle.arrow_forwardDarcy and Raul are having difficulty conceiving a child. Darcy ovulates every 28 days, and Raul’s sperm count is normal. If we could observe Raul’s sperm about an hour after ejaculation, however, we’d see that they appear to be moving only sluggishly. When Raul’s sperm eventually encounter Darcy’s oocyte, they appear to be incapable of generating an adequate acrosomal reaction. Which process has probably gone wrong?arrow_forward
