Verified step by step guidance1
Understand that a typical human somatic cell is a diploid cell, meaning it contains two sets of chromosomes, one from each parent.
Recognize that humans have a total of 46 chromosomes in their somatic cells.
Divide the total number of chromosomes (46) by 2 to determine the number of pairs of homologous chromosomes.
Each pair consists of one chromosome from the mother and one from the father, making them homologous.
Conclude that there are 23 pairs of homologous chromosomes in a typical human somatic cell.
