Question

During Spermatogenesis, the second meiotic division does not further reduce the chromosome number. Why is it called a meiotic division?

Answer 1

Spermatogenesis:

1. Spermatogenesis is the formation and maturation of sperm cells within the testes, the male reproductive organs.
2. While meiosis II is an equational division, meiosis I is a reductional division that results in a halving of the number of chromosomes.
3. As a result, there is the same number of chromosomes (23).
4. Because of this, the second division is just mitotic.
5. But because meiosis (which reduces the number of chromosomes) is necessary and because both divisions result in the creation of sperm, they are collectively referred to as meiotic division.
