Answer

Brief Explanations:

A gene pool is the set of all genes in a population. Deaths due to old - age are a normal part of life - cycle and are not likely to significantly alter the frequencies of alleles in the gene pool compared to other factors. Pesticide poisoning can cause non - random death and remove certain genotypes from the population. Migration to a new habitat can introduce or remove alleles through gene flow. Genetic mutations introduce new alleles into the gene pool.

Answer:

A number of chipmunks die due to old age.
