Question

organizing data about expressed traits quick check
what is one similarity between genetic drift and gene flow? (1 point)
○ they both occur in a population by chance.
○ they are both caused by natural disasters, such as hurricanes.
○ they are both caused by the migration of species.
○ they both cause a change in the frequency of traits in a population.

Explanation:

Genetic drift (random changes in trait frequencies) and gene flow (trait transfer via migration) both alter trait frequency in a population. Chance only describes genetic drift; natural disasters are a genetic drift subset (bottleneck effect); migration only causes gene flow.

Answer:

D. They both cause a change in the frequency of traits in a population.
