Q: Dominant alleles rarely cause what type of disorders, since the mutant allele is likely to die out of the population?


Read this paragraph and choose the correct option from the provided answers:

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.
