In the Following Figure,two Populations of One Species of Fruit

question 32

Multiple Choice

In the following figure,two populations of one species of fruit flies were raised for several generations on different nutrients (starch and maltose) .Then the members of the two populations were reintroduced and the mating frequencies of flies from the two different populations were recorded.Which of the following is true?

• A) After only a few generations,these two populations have undergone speciation because they no longer mate with each other at high levels.
• B) The two populations are in the early stages of reproductive isolation because male flies are more likely to mate with female flies that were raised on the same medium.
• C) Fruit flies grown on starch for several generations are no longer capable of consuming maltose.
• D) The original population of fruit flies actually consisted of two different species of fruit flies.When hybridization occurred between the two populations,only sterile offspring were produced.
