How can alleles that cause serious diseases, such as sickle cell disease, still provide an advantage to the human population?

Sagot :

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.

This allele is lethal in homo-zygous individuals, thereby tending to be eliminated from the population.

However, in regions where malaria is endemic, the presence of carriers individual having the sickle cell allele is advantageous to prevent this disease.
