Question

if a frog has 30 chromosomes in its skin cells, how many chromosomes are in his gametes?

Explanation:

Step1: Determine cell type

Skin cells are somatic (body) cells, which are diploid (\(2n\)).

Step2: Recall gamete ploidy

Gametes (sperm/egg) are haploid (\(n\)).

Step3: Calculate chromosome number

If \(2n = 30\), then \(n=\frac{30}{2}=15\).

Answer:

15
