Secondary Spermatocytes Each Contain

Question

Secondary spermatocytes each contain
A) 23 chromosomes.
B) 23 pairs of chromosomes.
C) twice the diploid number of chromosomes.
D) 46 pairs of chromosomes.
E) 46 chromosomes.

Accepted Answer

Secondary spermatocytes are formed after the first meiotic division of primary spermatocytes. During this division, the chromosome number is reduced by half, so each secondary spermatocyte contains 23 chromosomes, which is half of the diploid number (46) present in primary spermatocytes.
