Question

Which best describes oogenesis and spermatogenesis?

Answer 1

The answer is B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.

Gametogenesis is a process in which gametes are produced. Oogenesis is a process in which egg cells are produced and spermatogenesis is a process in which sperm cells are produced. Both processes include meiosis.

Original diploid cell (primary oocyte or spermatogonium) has 46 chromosomes. After meiosis I, there are two haploid cells. After meiosis II, there are 4 haploid cells because meiosis II is similar to mitosis. The difference between spermatogenesis and oogenesis is that those 4 cells after meiosis II in spermatogenesis are all sperm cells, and in oogenesis only one of them is egg cell.

Answer 2

Meiosis

Spermatogenesis is the meiotic process of the gametes of the sperm cells. While the oogenesis is the biological process of creating egg cells. This two cells are the product of the meiosis cell division which functions for the gamete production.
