allelic complementation

Quick Reference

The production of nearly normal phenotype in an organism carrying two different mutant alleles in trans configuration. Such complementation is sometimes caused by the reconstruction in the cytoplasm of a functional protein from the inactive products of the two alleles. When such a phenomenon can be demonstrated by mixing extracts from individuals homozygous for each allele, the term in vitro complementation is used. Synonymous with intra-allelic complementation. See Chronology, 1963, Schlesinger and Levinthal; alcohol dehydrogenase, alkaline phosphatase, transvection.
