Spermatogenesis _________ .

a. involves a type of cell division limited to gamete production

b. involves a two-part process called meiosis I and mitosis II

c. is another term for ejaculation

d. results in the formation of diploid cells

Expert Solution

Spermatogenesis is the process of production of sperms. The immature sperm cell undergoes successive mitotic and meiotic divisions in order to produce spermatozoa.

There are basically three steps involved:

1) Spermatocytogenesis via Mitosis

2) Meiosis I and Meiosis II

3) Spermiogenesis

Option a. Spermatogenesis involves types of cell divisions (Mitosis and Meiosis) which are limited to gamete production. As the question, it is written cell division. I am assuming it to be cell divisions. CORRECT OPTION

Option b. Spermatogenesis does involve Meiosis I and Meiosis II, but in the beginning there occurs Mitosis. (See diagram) The statement is incomplete. Hence, INCORRECT OPTION

Option c. Ejaculation is the release of semen from male reproductive part. INCORRECT OPTION

Option d. At the end of spermatogenesis, haploid spermatozoa are produced. (See diagram) INCORRECT OPTION
