Question

random changes of allele frequency in a population between generations is an example of:
○ genetic drift.
○ behavioral isolation.
○ genotype change.
○ mechanical isolation.
○ ecological isolation.

Explanation:

Genetic drift is defined as the random fluctuation of allele frequencies in a population over successive generations. Behavioral, mechanical, and ecological isolation are types of reproductive barriers, not changes in allele frequency. Genotype change refers to alterations in an individual's genetic makeup, not population-level allele frequency shifts. Thus, the correct answer is genetic drift.

Answer:

genetic drift.
