State
A locus is a gene's specific position on a chromosome; homologous chromosomes are a matched pair, one from each parent, carrying the same genes at the same loci.
Show
Each of a person's 23 chromosome pairs is homologous, one member inherited from each biological parent.
Watch for
Homologous chromosomes carry the same genes at matching loci, not necessarily the same alleles there.
