In a species of water snake has populations on the mainland and on an island, snakes are regularly washed from the mainland to the island where they become part of the breeding population on the island. For the island population, this violates the assumption of ______________________ because the evolutionary mechanism of________________ is present.

- Dog breeds are an example of artificial selection, which means ______ selected for certain traits in dogs fill the balnkarrow_forwardThe following experiment is used for the following question. A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers, but caterpillars that hatch in summer feed on oak leaves and look like oak twigs. How does the same population of moths produce such different-looking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below. Temperature Springlike Springlike Summerlike Summerlike Day Length Springlike Summerlike springlike summerlike In each of the…arrow_forwardThe Tibetans and Han Chinese share several genetic traits and DNA. However the EPAS1 gene which increases the ability of red blood cells carry oxygen even in low environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is commonly in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in 3-5 sentencesarrow_forward
