A primary spermatocyte (diploid, 46 chromosomes) undergoes the first meiotic division to produce:
AOne ovum and three polar bodies
BTwo haploid secondary spermatocytes with 23 chromosomes each
CTwo diploid daughter cells
DFour haploid spermatids
Answer & Solution
Correct answer: B. Two haploid secondary spermatocytes with 23 chromosomes each
Meiosis I of a primary spermatocyte → **two equal haploid secondary spermatocytes (23 chromosomes each)**. Each then undergoes meiosis II to produce two spermatids — yielding four spermatids per primary spermatocyte.
