Question

6 a somatic (body) cell of a human contains 46 total chromosomes. how many chromosomes are present in a human gamete (egg cell)? a 46 b 23 c 92 d 47

Explanation:

Step1: Identify cell type ploidy

Somatic cells are diploid ($2n$), so $2n = 46$.

Step2: Calculate gamete chromosome count

Gametes are haploid ($n$), so $n = \frac{2n}{2} = \frac{46}{2}$

Answer:

B. 23
