A fungus goes through a population of worms killing most of them. It appears that this fungus kills any worm that becomes infected. No worms have any genetic advantages. A small group of worms survives by sheer luck. And by coincidence (i.e. not related to the fungus) these worms all have a rare allele for blue skin.

Question
A fungus goes through a population of worms killing most of them. It appears that this fungus kills any worm that becomes infected. No worms have any genetic advantages.
A small group of worms survives by sheer luck. And by coincidence (i.e. not related to the fungus) these worms all have a rare allele for blue skin. The blue color seems to have no affect in their survival nor reproduction.
The survivors reproduced and the population gets back to its normal number. But most worms now have the blue skin allele. The increase in this allele was due to:
Group of answer choices
natural selection
non-random mating
genetic drift
