Chromosome that is more or less identical to a second chromosome that is also present within a single diploid cell.
Homologues, also known as homologous chromosomes, generally are sourced from separate parents in sexually reproducing pecies. Of a pair of homologous chromosomes, one of these two chromosomes thus was sourced from an individual's mother whereas the other comes from the individual's father.
Homologues are identical in size, banding patterns, location of the centromere, and in terms of what loci are present, but not in terms of what alleles are present.
These concepts apply to autosomes but not necessarily to pairs of sex chromosomes, i.e., X and Y, since the latter tend to not be identical in terms of size, banding patterns, location of centromere, or what loci are present.
