Question

in a population of gray squirrels, some individuals are larger than others. How is genetic drift likely to affect this population without any pressure from the environment?

Answer 1

Genetic drift

Step-by-step explanation:

is the process by which the frequency of alleles in a population can change randomly over time. In a population of gray squirrels, genetic drift is likely to lead to a decrease in the frequency of alleles associated with larger size over time. This is because, due to random sampling, some individuals carrying alleles associated with larger size are more likely to be excluded from the population than those carrying alleles associated with smaller size. This means that, over time, the population is likely to become smaller on average. This is known as a random genetic drift, and it is caused by chance alone, without any pressure from the environment.
