Asked by Tyson Landenberger on Apr 23, 2024
Which of the following would likely increase the likelihood of fixing a beneficial allele in a population of finite size?
A) a higher starting frequency to decrease likelihood of drift
B) a larger excess fitness to increase selection for the beneficial allele
C) a larger population size because selection will be greater in a larger population
D) all of the above
E) none of the above
Fixing Beneficial Allele
The process by which a beneficial genetic variation becomes established, or fixed, in a population, often leading to evolutionary advantages.
Starting Frequency
Refers to the initial proportion or occurrence rate of a particular genetic variant or allele within a population at the beginning of a specified period.
Excess Fitness
The additional reproductive success of individuals with a certain genotype compared to the average reproductive success in the population.
