Verified step by step guidance1
Understand that human cells can be either haploid or diploid. Haploid cells, like gametes (sperm and egg), contain one set of chromosomes, while diploid cells contain two sets.
Recall that humans have 23 unique chromosomes in one set (haploid number). These include 22 autosomes and 1 sex chromosome.
Since somatic cells (like skin cells) are diploid, they contain two sets of chromosomes, one from each parent.
Calculate the total number of chromosomes in a diploid cell by multiplying the haploid number by 2: \(2 \times 23\).
Conclude that the typical number of chromosomes in a human diploid somatic cell is the result of this calculation.
