"WebThe reproductive fitness of a heterozygote is only affected if the phenotype is altered. Thus, genetic selection can act on heterozygotes for a dominant mutation. If the heterozygotes for a disease mutation have a low reproductive fitness, the mutant allele will only be maintained in the population by the process of new mutation. " - Highest fitness biology
