Term used to describe the phenomenone where only black and grey rabbits survive and rest are killed randoml is called Genetic Drift..
What is genetic drift?
- As a result of a chance or random event, the frequency of an allele in a population drifts over time compared to the frequency of the other alleles. this is termed as genetic drift.
- Here, the rabbits with other coat colors were randomly killed off due to the disease which increased the frequency of the black and grey coat allele and hence the population drifts from multicolored coats to only black and grey colored rabbit coats.
Hence the correct option here will be 2. Genetic Drift
other options are incorrect because:
- Artificial selection is inducing the desired traits artifically which is not possible because the disease was a random event and not induced by humans.
- Natural selection is the survival of the fittest of the alleles and elimination of less fitter alleles. here it is not mentioned whether Black and grey coats were more fitter to survive than other coats
- Genetic modification is a human made procedure and did not occur here.
