What is regarded as a strong evolutionary mechanism for changing allelic frequencies?
A)selection
B)migration
C)mutations
D)recombination

Question

Quizplus · Accepted Answer

Selection is a strong evolutionary mechanism for changing allelic frequencies because it acts directly on the traits of an organism, promoting or removing those traits from the gene pool based on their fitness in a given environment. This process can rapidly shift the relative frequencies of different alleles within a population over time. Migration (B) can also change allelic frequencies, but it is generally not considered as strong a mechanism as selection. Mutations (C) and recombination (D) can introduce new genetic variation into a population, but their effects on allelic frequencies are generally slower and more subtle than selection.
