Amalaria outbreak causing allele frequencies to change is an example of: nonrandom mating. the bottleneck effect. genetic drift. natural selection. differential migration.
THIS IS THE BEST ANSWER 👇
Answer: Natural selection.
Charles Darwin introduced the concept of natural selection. Consistent with this concept, in a given environment the organisms with better adaptations have a higher chance of surviving and subsequently leaving a larger number of offspring. When a malaria outbreak occurs, the frequencies of the alleles change. and only the organisms that have the alleles that help them survive this outbreak due to resistance to malaria infection will be selected by nature and so this is an example of natural selection.
