Solution
Given enough time, genetic drift will eventually cause the loss of alleles.
Here's why:
-
Genetic drift is a mechanism of evolution that causes random changes in the frequency of alleles in a population.
-
Over time, these random changes can lead to the loss of certain alleles, especially in small populations. This is because when an individual with a certain allele does not reproduce or their offspring do not survive, that allele can be lost from the population.
-
As this process continues over many generations, it can eventually lead to the loss of all individuals carrying a certain allele, resulting in the loss of that allele from the population.
-
Therefore, given enough time, genetic drift can lead to the loss of alleles in a population.
