Question

a human skin cell contains 46 chromosomes. how many chromosomes are present in a human egg cell? a 23 b 46 c 92 d 138

Explanation:

Human skin cells are somatic cells and are diploid (\(2n\)), containing 46 chromosomes. Egg cells are gametes and are haploid (\(n\)). Haploid cells have half the number of chromosomes as diploid cells. So, \(n=\frac{2n}{2}=\frac{46}{2} = 23\).

Answer:

A. 23
