Complementary mutation
WebThis will be the case for mutations in different genes—intergenic complementation—and, in rare instances, for different mutations in the same gene—intragenic complementation. Retention of the mutant phenotype is a priori evidence that the mutations occurred in the same genetic locus as neither parent genome can correct for the defect of the other.
