PLEASE HELP ASAP 46. If a species has experienced a genotype mutation that has greatly reduced its population size, but later the population increases, which of the following is most likely the consequence on the surviving population?

Organisms in the surviving population will be genetically superior, which will strengthen the population.
The natural selection of the surviving population will move from a normal selection to a disruptive selection.
The surviving population will be very different than the original population.
The surviving population will have very little genetic variation.
