What is an allelic mutation?

Allelic heterogeneity is the phenomenon in which different mutations at the same locus cause the same phenotype. These allelic variations can arise as a result of natural selection processes, as a result of exogenous mutagens, genetic drift, or genetic migration.

In this regard, what is complementation test in genetics?

Since the mutations are recessive, the offspring will display the wild-type phenotype. A complementation test (sometimes called a "cis-trans" test) can be used to test whether the mutations in two strains are in different genes. Complementation will not occur if the mutations are in the same gene.
