one of two or more closely linked genes on a chromosome that appear to function as a single allelic pair but occupy distinct, nearly corresponding loci on homologous chromosomes. Such gene pairs produce a mutant effect in the diploid state when located on homologous chromosomes but are capable of being separated by crossing over during meiosis to produce a wild-type effect when recombined on either of the homologues. pseudoallelic, adj., pseudoallelism, n.
one of two or more genes that are seemingly allelic, but which can be shown to have distinctive but closely linked loci.
