Verified step by step guidance1
Understand that human somatic cells are all the body cells except the gametes (sperm and egg cells). Somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent.
Recall that humans have 23 pairs of chromosomes, which means each pair consists of two homologous chromosomes.
Calculate the total number of chromosomes in a somatic cell by multiplying the number of pairs by 2: $23 \times 2$.
Recognize that the total number of chromosomes in a normal human somatic cell is the sum of all chromosomes from both sets.
Conclude that the typical chromosome number in a normal human somatic cell is 46.
