Phenotype mutation
WebMay 29, 2024 · How Do Mutations Affect Genotype And Phenotype? For the mutant phenotype to occur, both alleles must carry the mutation. Dominant mutations lead to a mutant phenotype in the presence of a normal copy of the gene. The phenotypes associated with dominant mutations may represent either a loss or a gain of function.
