Question

A small population of prairie dogs lives in a habitat that does not undergo any changes for a long period of time. How is genetic drift likely to affect this population?

Answer
a)It will accelerate the appearance of new traits in members of the population who are more “fit” for survival.
b)It will allow most members of the population to live longer because they will inherit many beneficial adaptations.
c)It will increase genetic diversity as new alleles are introduced to the gene pool from neighboring populations.
d)It will reduce genetic diversity by decreasing the frequency of some alleles a ...?

Answer 1

The correct answer would be d) It will reduce genetic diversity by decreasing the frequency of some alleles.

Genetic drift is one of the methods of evolution in which frequency of certain genotype or alleles is reduced in a population.

It mainly occurs when population size reduces to a very small size due to a random event such as natural disaster, over-hunting et cetera.

The decrease in population size results in the loss of certain alleles or genotype from the population.

Answer 2

The correct answer to this question is d. It will reduce genetic diversity by decreasing the frequency of some alleles and increasing the frequency of others. This is how genetic drift likely to affect this population. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
