Question

Do we get 8 spermatozoa from one primary spermatocytes and 4 spermatozoa from one secondary spermatocytes ?

Answer 1

1 spermatogonium grows to form 1 primary spermatocyte which divides by meiosis 1 to form 2 secondary spermatocytes. These divide by meiosis II to form 4 spermatids which mature by spermiogenesis to form 4 spermatozoa.
