Question
Q1) How might the timing of when fruit ripens be important in the sympatric speciation of fruit maggot flies? See Section 24.3 (Page 488) .
A)Apple fruit ripening earlier allows for increased reproductive output for the flies.
B)Apple fruit ripens earlier than hawthorn fruit, allowing the apple flies to immediately mate with the later-emerging hawthorn flies.
C)Apple fruit ripens earlier than hawthorn fruit, reducing the interaction of the fly species in time.
D)Apple fruit ripening earlier is a vicariant event.

D)Apple fruit ripening earlier is a vicariant event.
Explanation / Answer
ANSWER C)Apple fruit ripens earlier than hawthorn fruit, reducing the interaction of the fly species in time.
Explanation:
1) Apple flies respond more strongly to apple scents whereas hawthorn flies respond strongly to hawthorn scents.
2) Hawthorn flies avoid apple scent and apple flies avoid hawthorn scent
3) Both Apple flies and hawthorn flies do not show any response to a mix of both scents or no scent at all.
