pseudoallele /-əlēl″/ [Gk, pseudes + allelon, of one another] , 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.
