The answer is <span>The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
Mentioned organisms are diploid (2n) and they have 2 sets of chromosomes in their somatic cells. However, their gametes (egg cells and sperms) are haploid (n) and have only 1 set of chromosomes.
After fertilization, a haploid egg cell from a mother and a haploid sperm from a father fuse and form diploid zygote:
n + n = 2n
