Question

the gametes of african elephants contain 28 chromosomes. how many chromosomes would be found in a muscle cell of the same organism? 28 84 14 56

Explanation:

Step1: Recall cell - type chromosome relationship

Gametes are haploid cells. Somatic cells like muscle cells are diploid.

Step2: Determine diploid number

If haploid number ($n$) of chromosomes in gametes is 28, diploid number ($2n$) in muscle cells is $2\times28$.
$2\times28 = 56$

Answer:

56
