Understand that a human somatic cell is any cell forming the body of an organism, excluding germ cells.
Recognize that human somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent.
Recall that the diploid number of chromosomes in humans is 46, which includes 22 pairs of autosomes and 1 pair of sex chromosomes.
During mitosis, a somatic cell divides to produce two identical daughter cells, each with the same number of chromosomes as the original cell.
Therefore, a human somatic cell undergoing mitosis starts with 46 chromosomes, which is the diploid number for humans.
