Which of the following is NOT true regarding spermatogenesis?
Initial spermatozoa formed are not mobile and cannot fertilize.
Spematogonia have diplold chromosome.
Spematocyte undergoes two rounds of division to produce 4 diploid sperm
Some of the spermatogonia become reservoir cells
Spematogonia breaks away from the basement membrane to develop Into sperm.
TRUE OF FALSE
Primary spermatocytes are diploid in number like spermatogonia while spermatocytes are haploid in number.
Spermatogenesis is the final stage of reproductive cell division by which there is the development of haploid spermatids into sperm. Spermiation is the event by which sperm are released from their connections to Sertoli cells.
Digestive secretions from the small intestine complete the digestion of carbohydrates, proteins, and lipids. Bacteria in the large intestines produce minerals and nucleic acids.

- 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.arrow_forwardAfter learning about the reproductive systems, how would advise a couple with following concern: "If we do not want a baby for next two years, how can we calculate the safe sex period?" She shares that her cycle is regular but not standard 28 days long cycle (so the standard explanation form different sources won't work unless you think critically)! At what time of the female cycle is she most likely to prevent fertilization of her ovulated egg? Consider the fact that her cycle is not 28 days but longer or shorter (you pick). Do males have any time (in their cycle- if any) when their gametes would not be able to fertilize the egg? In other words when can intercourse lead to least chance of pregnancy?

If both persist, the baby will have an intersex condition.
