Question

How might the timing of when fruit ripens be important in the sympatric speciation of fruit maggot flies? See Section 24.3 (Page 488) .

How might the timing of when fruit ripens be important in the sympatric speciation of fruit maggot flies? See Section 24.3 (Page 488) .

Apple fruit ripens earlier than hawthorn fruit, allowing the apple flies to immediately mate with the later-emerging hawthorn flies. Apple fruit ripens earlier than hawthorn fruit, reducing the interaction of the fly species in time. Apple fruit ripening earlier is a vicariant event. Apple fruit ripening earlier allows for increased reproductive output for the flies.

Explanation / Answer

Answer: Option B is correct.

Explanation:

Apple fruits ripen/drop earlier than hawthorn fruits. This reduces the interaction of the fly species in time. This allows for sympatric speciation (speciation without geographic isolation).
