Answer 1

Natural selection is a type of selection that exists between certain inherited conditions and environmental pressures.

How does malaria and sickle cell anemia show natural selection?

The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others. Natural selection is a non-random difference in reproductive output among replicating entities.

It turns out that HbS carriers have been naturally chosen in these regions because the trait gives some malaria resistance. When they are infected with the malaria parasite, their red blood cells, which include some aberrant hemoglobin, have a propensity to sickle. The malaria life cycle intensifies both natural selection and random genetic drift.
