Certain alleles may cause serious diseases in a given environment but they may also be beneficial in different environmental conditions. It is a principle of natural selection.

Natural selection and alleles

Natural selection refers to the differential survival and reproduction of an organism in a given environment.

Certain alleles such as the allele of sickle cell disease show an evolutionary advantage in specific environmental conditions.
