Question
Genetic drift is a change in the allele frequency of a population due to ______.
- Random chance
- Natural selection
- Non-random mating (sexual selection)
- Artificial selection
Hint:
Genetic drift is defined as a shift in the allele frequency of a population caused by random chance.
The correct answer is: Random chance
- Genetic drift can be described as the change in the frequency of the allele of a population cause due to random chances.
- Genetic drift can result into complete disappearance of the gene and reduces the genetic variation in the population.
- It also can result into expresseion of rare alleles.
