During spermatogenesis, a single primary spermatocyte (2n) ultimately yields how many functional spermatozoa?
A1 sperm
B2 sperms
C4 sperms
D8 sperms
Answer & Solution
Correct answer: C. 4 sperms
Primary spermatocyte (2n) → meiosis I → two secondary spermatocytes (n) → meiosis II → four spermatids (n) → spermiogenesis → **four** functional motile sperms. (Contrast with oogenesis: one primary oocyte → one functional ovum + 3 polar bodies.)
