1. Genes that are located very close together on a chromosome and produce similar or nearly identical effects, but can be separated by recombination and are not true alleles of the same locus.
Usage: genetics; plural form; singular is pseudoallele; technical term used in molecular and classical genetics

Examples

• Researchers discovered that the mutations were pseudoalleles rather than true alleles of the same gene.
• The pseudoalleles could be separated through rare recombination events in the laboratory.
• In Drosophila studies, pseudoalleles helped scientists understand the fine structure of genes.
• The existence of pseudoalleles challenged the classical definition of a gene as an indivisible unit.
• Geneticists used pseudoalleles to map the precise locations of closely linked genetic loci.
