How many chromosomes are present in (i) a human secondary spermatocyte, and (ii) a mature spermatozoon?
A(i) 46, (ii) 46
B(i) 23, (ii) 23
C(i) 46, (ii) 23
D(i) 23, (ii) 46
Answer & Solution
Correct answer: B. (i) 23, (ii) 23
Meiosis I converts the diploid primary spermatocyte (2n = 46) into two **haploid** secondary spermatocytes (n = 23). Meiosis II then produces four haploid spermatids (n = 23) which mature into spermatozoa with **23** chromosomes each.
