Dominant alleles rarely cause what type of disorders, since the mutant allele is likely to die out of the population?
cancers
mutations
sex-linked disorders
genetic disorders
Few genetic disorders are controlled by dominant alleles. A mutant dominant allele is expressed in every individual who inherits even one copy of it. If it causes a serious disorder, affected people may die young and fail to reproduce. Therefore, the mutant dominant allele is likely to die out of the population.
