When males place their sperm in the females' spermathecae, fruit flies can start laying eggs (a process known as induction). Induced egg laying has the selection benefit of ensuring that a male fly's sperm is utilized for fertilization, which is beneficial for male flies.
- The spermatheca is an ectodermal organ that only develops in Queens and is not present in workers.
- Spermathecae gets sperm from the male during mating.
- Because it assures that a male fly's sperm is used for fertilization, induced egg laying for male flies has this benefit.
Thus from the above points, we can conclude that egg laying in the fruit flies had an adantage.

Explanation:
This phase occurs before mitosis, it is here that the cell's DNA is copied in preparation for mitosis. This phase is also known as the metabolic phase (previously called the 'resting phase'), because it is during this phase that the cell gets it nutrients, breaks them down, and grows. It is therefore best to arrest the cell in this phase before any modifications happen to the cell during mitosis, and it is during this phase that the cell's metabolism is at its high functionality.
Delayed phase preference.
