Multiple Choice

If a sperm cell contains 8 chromosomes, how many chromosomes would be found in a typical somatic (body) cell of the same organism?

Verified step by step guidance

Understand that sperm cells are gametes, which are haploid cells containing half the number of chromosomes of a typical somatic cell.

Identify that the sperm cell has 8 chromosomes, so this number represents the haploid chromosome number (n = 8).

Recall that somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent.

Use the relationship between haploid and diploid numbers: diploid number (2n) = 2 \times haploid number (n).

Calculate the diploid chromosome number by multiplying 8 (haploid) by 2, which gives the number of chromosomes in a typical somatic cell.
