question 37

Multiple Choice

Drosophila pseudoobscura and D.persimilis are two species of flies that live in the western United States.The geographic range of D.persimilis,which is much smaller than that of D.pseudoobscura,is enclosed within the range of D.pseudoobscura.Findings by Mohamed Noor and others show that D.pseudoobscura taken from areas that overlap with D.persimilis are less likely to mate with D.persimilis than are the D.pseudoobscura flies from populations that do not experience D.persimilis.What is the most likely explanation for these results?

• A) Reinforcement
• B) The Dobzhansky-Muller model
• C) Temporal isolation
• D) Habitat isolation
• E) Gametic isolation
