Egg laying in fruit flies can be triggered (induced) when males deposit their sperm in the spermathecae of the females. what is the selective advantage of induced egg laying for the male flies?

The advantage of the induced egg laying is that the sperm male flies is normally used for fertilization.

Fruit flies usually lay egg near the surface of fermenting foods or organic materials an dthey there eggs under the lid and the tiny larvea enter the container upon hatching. Thus, the tiny larvea feed near the surface of the fermenting mass and the advantage of the induced egg laying is that the sperm male flies is normally used for fertilization.

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs. 

explanation:

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
