Being one of a pair of chromosomes, one from the female parent and one from the male parent, that have genes for the same traits in the same positions. Genes on homologous chromosomes may not have the same form, however.

A pair of homologous chromosomes contains chromosomes of similar length, gene position, and centromere location. Chromosomes are important molecules because they contain DNA and genetic instructions for the direction of all cell activity. They also carry genes that determine individual traits that can be inherited through reproduction. A human karyotype shows the complete set of human chromosomes. Each human cells contain 23 pairs of chromosomes or 46 total. Every chromosome pair represents a set of homologous chromosomes.
