Question

Quizplus · Accepted Answer

The 22 pairs of chromosomes in humans that contain most of the genes that affect somatic characteristics are called autosomal chromosomes. Alleles refer to different versions of the same gene. Heterozygous and homozygous chromosomes describe the presence of different or identical alleles, respectively, at a specific genetic locus. Homologous chromosomes refer to matching chromosomes (one from each parent) that carry the same genes in the same order.
