Gametogenesis and Structure of Gametes: Overview
This topic covers concepts such as sperm, spermial mitochondria, oogonia, primary oocytes and secondary oocyte.
Important Questions on Gametogenesis and Structure of Gametes
In which of the following phases all organisms have to pass through it before they can reproduce sexually?
A human ovum completes its second meiosis:
Germ cells in human males and ova in females are:
How many polar bodies would be formed during the formation of 10 menstrual cycles, considering one secondary oocyte was formed in each cycle?
For normal fertility how many percentage of sperms must have normal shape and size ?
One oogonium forms
What is likely to happen to the polar bodies formed after each meiotic cycle in oogenesis? Give a reason to support your answer.
In an individual with low testosterone levels. if the semen sample of such an individual is collected, what is likely to be observed?
Gametogenesis is the process of production of gametes. In males, it is spermatogenesis and in females it is oogenesis. The cells in the germline that undergo meiosis, primary spermatocytes or primary oocytes, are derived from the zygote by a long series of mitosis before the onset of the two meiotic cycles to form the mature gametes. Testosterone is an androgen that plays an important role in the formation and release of sperm from the seminiferous tubules. What is the count of chromosomes after the first and second meiotic divisions in the formation of sperms? Give a reason to support your answer.
