Answer:
As comic is not available, lets try to understand genetic drift generally.
Explanation:
Genetic drift can be described as the changes in the allele frequency or changes in the genotype variations of a population due to certain reasons such as death etc. In genetic drift, a particular genotype of a species starts to decrease, while the other genotype might start to increase. For example, imagine there are 6 colours of rabbits to be seen in a population. An event such as a diseases takes over which results in death of most of the rabbits. Only a few rabbits are left having brown and grey colour. Hence, the genetic drift changes from 6 to only 2.
