Verified step by step guidance1
Understand that homologous chromosomes are pairs of chromosomes in a diploid organism, where one chromosome of each pair is inherited from each parent.
Recall that humans have a total of 46 chromosomes in their somatic cells, which are organized into pairs.
Divide the total number of chromosomes (46) by 2 to determine the number of homologous pairs, since each pair consists of two chromosomes.
Recognize that the result of this division gives the number of homologous chromosome pairs in humans.
Conclude that humans typically have 23 pairs of homologous chromosomes, which includes 22 pairs of autosomes and 1 pair of sex chromosomes.
