Homologous: Corresponding in structure, position, origin, etc., such as the feathers of a bird and the scales of a fish, the antigen and its specific antibody, the allelic chromosomes.

Diploid: A cell with a full set of genetic material, consisting of chromosomes in homologous pairs and thus having two copies of each autosomal geneti locus.
