During Spermatogenesis, One Spermatogonium Containing 46 Chromosomes Yields __________________

Question

During spermatogenesis, one spermatogonium containing 46 chromosomes yields __________________
A)16 spermatozoa, each containing 23 chromosomes.
B)2 spermatozoa, each containing 23 chromosomes.
C)1 spermatozoon containing 46 chromosomes.
D)1 spermatozoon containing 23 chromosomes, and a polar body containing the other 23 chromosomes.

Accepted Answer

During spermatogenesis, one spermatogonium undergoes mitotic division to produce two cells, which then each undergo two rounds of meiotic division. This process results in four spermatids from each original cell, totaling eight spermatids, which further develop into eight mature spermatozoa, each containing 23 chromosomes. The initial statement incorrectly states the yield as 16 spermatozoa; the correct yield from one spermatogonium, after considering the entire process, is actually 4 mature spermatozoa, each with 23 chromosomes.
