Answer:
A primary spermatocyte produces 4 mature sperm cell(s); a primary oocyte produces 1 mature egg(s).
Explanation:
Meiosis in the diploid primary spermatocyte produces two secondary spermatocytes. These secondary spermatocytes are haploid cells. Each of them enters the meiosis-II and produces two spermatids. Therefore, meiosis in one primary spermatocyte produces a total of 4 spermatids. One the other hand, meiosis in a primary oocyte produces one secondary oocyte and one polar body. Completion of meiosis-II in the secondary oocyte gives rise to one egg cell and second polar body.
Answer:
1. 4 Mature sperm cell
2. 1 mature ovum
Explanation:
The process of gamete formation known as gametogenesis produces the gametes by the process of meiosis.
The process of sperm cell production is known as spermatogenesis which produces four spermatids by the process of meiosis from the primary spermatocyte.
The primary spermatocyte undergoes meiosis I and produces 2 Secondary spermatocytes which undergoes meiosis II and forms 4 spermatids which mature and form 4 sperm cells.
The process of oogenesis form only 1 mature ovum cell from the primary oocyte as the primary oocyte undergoes meiosis I and form a secondary oocyte and polar body and arrests. The secondary oocyte undergoes meiosis II but arrests until fertilization which form 1 mature ovum and second polar body.
Thus, 4 Mature sperm cell and 1 mature ovum is the correct answer.
