Answer:

founder effect

Explanation:

When a few individuals from a population migrate to some new habitat and start a new population, the gene pool of the new population may not have the same allele frequencies as that of the original population. This change in the allele frequency of the new population is called the founder effect. In the given population, the increased frequency of the AB+ phenotype might have resulted from the founder effect. This is a chance event that occurs when a few individuals with a small fraction of genetic variations found a new population.

poizon [28]

Answer:

Natural selection

Explanation:

Sexual selection refers to the natural selection where the allele frequencies of a population are changed due to nonrandom mating between the individuals. Certain preferences for the mate by organisms result in sexual selection. It is mostly exhibited by females.

For example, peahen prefers the peacocks with elaborate tail features as their mate. The sexual selection also occurs when there is competition among the members of the same sex for a mate. This type of sexual selection is mostly exhibited by males and results in fighting and display.
