Understand that chromosomes are structures within cells that contain DNA. In humans, chromosomes are found in pairs.
Recognize that human body cells, also known as somatic cells, are diploid. This means they contain two sets of chromosomes, one set inherited from each parent.
Recall that humans have 23 pairs of chromosomes in their somatic cells. This includes 22 pairs of autosomes and 1 pair of sex chromosomes.
Calculate the total number of chromosomes in human somatic cells by multiplying the number of pairs by two: \( 23 \times 2 \).
Conclude that the total number of chromosomes in human somatic cells is 46.
