In Which Type of Scenario Would Genetic Drift Have a More

Question

In which type of scenario would genetic drift have a more significant effect?
A) A population with 1,0000 individuals and an effective population size of 300
B) A population with 1,0000 individuals and an effective population size of 30
C) A population with 100 individuals and an effective population size of 30
D) A population with 10,000 individuals and an effective population size of 300

Accepted Answer

Genetic drift has a more significant effect in smaller populations. A population with 100 individuals and an effective population size of 30 is the smallest, making it most susceptible to genetic drift.
