The Himalayan Rabbit sports black fur on its extremities. This is due to an ancestral trait; the Himalayan Rabbits carry “temperature sensitive tyrosinase genes” which controls fur pigmentation. The rabbit’s ancestors, which would have had to survive in the cold Himalayan environment would have, through natural selection, favored a gene that allows for a darker pigmentation. Through evolution the Himalayan Rabbit passed down the genotype for a melanin producing gene, which activates in low temperatures, changing the individual rabbit’s phenotype to fit the climate.
So your answer is choice 1
