Question

The only difference between spermatogenesis and oogenesis, the processes that form sperm in males and eggs in females, is the creation of a new nucleus. Spermatogenesis completes the formation of mature sperm without a new nucleus, whereas in oogenesis, a new nucleus is constructed to safeguard the DNA in the resulting egg cell.

Answer 1

Spermatogenesis and oogenesis are both forms of gametogenesis that occur through meiosis. Spermatogenesis produces four sperm cells, while oogenesis produces one egg cell.

Step-by-step explanation:

In both spermatogenesis and oogenesis, gametes are formed through the process of meiosis. Spermatogenesis is the process of forming four sperm cells in males, while oogenesis is the process of forming one egg cell in females.

In spermatogenesis, one diploid cell gives rise to four haploid sperm cells. The sperm cells have a streamlined shape with a compact head and a flagellum tail for swimming and fertilizing an egg. On the other hand, in oogenesis, one diploid cell gives rise to one haploid egg cell, which is a much larger cell compared to sperm.
