Question

Question: Rabbits can exhibit a number of colors in their coats: black, white, tan, brown, red, and gray. A disease randomly kills off most of the population and leaves only black and gray rabbits. Future Generations are only black or gray. What is the term used to describe this phenomenon? (1 point)  

Responses:  

artificial selection  

natural selection

genetic modification

genetic drift

Answer 1

genetic drift — a random population bottleneck caused most alleles to be lost, leaving only black and gray by chance rather than selection.
