Question

How many secondary sperm a to yates are required to form 400 spermatozoa?

Answer 1

then from one primary spermatocyte, two secondary spermatocytes are formed by meiosis followed by the formation of spermatids and finally 4 spermatozoa. As each secondary spermatocyte results in the formation of two spermatozoa, 200 secondary spermatocytes will give rise to 400 spermatozoa.
