Question

if a muscle cell in a clown fish contains 28 chromosomes, a clown fish egg egg cell would contain:
a 56 chromosomes
b 7 chromosomes
c 28 chromosomes
d 14 chromosomes
e 42 chromosomes

Explanation:

Step1: Identify cell type ploidy

Muscle cells are somatic (diploid, $2n$) cells; egg cells are gametes (haploid, $n$).

Step2: Calculate haploid chromosome number

Haploid number = $\frac{\text{Diploid number}}{2}$
$\frac{28}{2}=14$

Answer:

D. 14 Chromosomes
