Verified step by step guidance1
Understand that somatic cells are any cells forming the body of an organism, excluding reproductive cells.
Recall that humans are diploid organisms, meaning they have two sets of chromosomes, one from each parent.
Each set of chromosomes in humans consists of 23 chromosomes, making a total of 46 chromosomes in somatic cells.
Visualize the chromosome pairs: 22 pairs are autosomes, and 1 pair consists of sex chromosomes (XX or XY).
Recognize that the number of chromosomes in somatic cells is consistent across all human body cells, except for gametes which have half the number.
