which of the following is least likely to change the gene pool of a population of chipmunks? a pesticide poisons and kills a large number of chipmunks. a group of chipmunks moves to a new habitat. a number of chipmunks die due to old age. a genetic mutation causes some of the chipmunks to have larger eyes.

Answer

Brief Explanations:

A number of chipmunks dying due to old - age is a natural and non - selective process that is least likely to cause a significant change in the gene pool. Pesticide poisoning is a form of selection pressure that can remove certain genotypes. Migration (a group moving to a new habitat) can change gene frequencies through gene flow. Genetic mutations introduce new genetic variation directly into the gene pool.

Answer:

A number of chipmunks die due to old age.
