Question

How many primary spermatocytes are required for the formation of 200 spermatozoa?
1) 50
2) 100
3) 25
4) 250​

Answer 1

Answer:

100 primary spermatocytes

Explanation:

Each secondary spermatocyte divides into two spermatids. Thus, 100 primary spermatocytes will undergo meiosis I to produce 200 secondary spermatocytes will give rise to 400 spermatids (after meiosis II); the 400 spermatids will ultimately form 400 spermatozoa.
