How many haploid cells will be formed after first meiotic division of one primary spermatocyte?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Two
The first meiotic division of one primary spermatocyte gives two haploid secondary spermatocytes.
Option (4) Two — Correct. Meiosis I is a reduction division: one diploid primary spermatocyte divides into two equal, haploid secondary spermatocytes.
NCERT Extract:
Gametogenesis – “… Each spermatogonium is diploid and contains 46 chromosomes. Some of the spermatogonia called primary spermatocytes periodically undergo meiosis. A primary spermatocyte completes the first meiotic division (reduction division) leading to formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes each.”
