If a sperm cell contains 8 chromosomes, it comes from an animal that has how many chromosomes in its somatic (body) cells?
A
32 chromosomes
B
4 chromosomes
C
16 chromosomes
D
8 chromosomes
Verified step by step guidance1
Understand that sperm cells are gametes, which are haploid cells containing half the number of chromosomes found in somatic (body) cells.
Identify that the sperm cell has 8 chromosomes, which means this number represents the haploid chromosome number (n).
Recall that somatic cells are diploid, meaning they have two sets of chromosomes, one from each parent, so the diploid number (2n) is twice the haploid number.
Set up the relationship: $2n = 2 \times n$, where $n$ is the haploid number (chromosomes in sperm) and $2n$ is the diploid number (chromosomes in somatic cells).
Calculate the diploid number by multiplying the haploid number (8 chromosomes) by 2 to find the total chromosomes in somatic cells.
