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.
