Question

Identify the evolutionary forces that can cause allele frequencies to change from one generation to the next.Check all that apply
A. Inbreeding
B. Mutation,
C.random genetic drift
D. migration
E. extinction
F. natural selection

Answer 1

Answer:

B. Mutation; C. Random genetic drift; D. Migration; F. Natural selection

Explanation:

B. Mutation:  Mutations resulting from substitution, addition or deletions of a nucleotide in a sequence can alter the gene. This can be carried over a population and may be have deleterious effects or increase fitness in a gene.

C. Random genetic drift: It is a change in allele frequency that occurs by chance, usually in a small population and is carried over generations.

D. Migration: Involves the flow of a gene in or out of a population, and this modifies the allele frequency.

F. Natural selection: When fitness-promoting alleles are favored and carried over to the next generation.
