noun
- One of two or more allelic variants at closely linked loci that behave as alleles in some crosses but show recombination in others.
Usage: genetics; technical
Examples
- Researchers discovered that what appeared to be a single gene was actually composed of multiple pseudoalleles.
- The pseudoalleles at this locus can recombine under certain conditions, revealing their distinct genetic locations.
- In Drosophila studies, pseudoalleles demonstrated that gene structure is more complex than previously thought.
- The fine-structure mapping of pseudoalleles helped establish the concept of the cistron.
- Pseudoalleles exhibit complementation patterns that distinguish them from true alleles at the same locus.
