Verified step by step guidance1
Understand the concept of somatic cells: Somatic cells are any cells forming the body of an organism, excluding germ cells which are involved in reproduction.
Recognize that human somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent.
Recall that humans have 23 pairs of chromosomes in their somatic cells. Each pair consists of one chromosome from the mother and one from the father.
Calculate the total number of chromosomes by multiplying the number of pairs by two: 23 pairs × 2 chromosomes per pair.
Conclude that the total number of chromosomes in human somatic cells is 46.
