Question

12 changes in allele frequency. what is the term used to describe the changes in allele frequencies in a population over generations? multiple choice directional selection founder effect non - random mating genetic drift

Explanation:

1. Directional selection: It is a type of natural selection that favors an extreme phenotype, but it is not the general term for changes in allele frequencies over generations.
2. Founder effect: It is a type of genetic drift that occurs when a new population is established by a very small number of individuals from a larger population, not the overall term for allele - frequency changes over generations.
3. Non - random mating: It affects the distribution of genotypes but not the definition of changes in allele frequencies over generations.
4. Genetic drift: Genetic drift refers to random changes in the allele frequencies of a population over generations.

Answer:

D. genetic drift
