Question

Certain traits become more or less common in a population as a result of differential reproductive success. which of the following examples describes the condition most likely to change the frequency of a trait within a population? explain why.
F. a large coal mine has been closed and abandoned, thus providing a brown bat population with a new hibernation site.



G. the food availability for a population of brown bats is severely diminished when a drought reduces the number of mosquitoes



H. injured brown bats are taken to a rehabilitation centre where the animals can recover before they are released into the wild.



I. after a gestation period of 50 days, female brown bats give birth to healthy pups that remain with their mothers for three weeks.

Answer 1

The most likely condition in here is the last option. When we talk about differential reproductive success we are talking about Darwin's natural selection and how the allele frequencies in a population may change and affect the natural mechanisms of the species. While the last option is the one who aproaches to what you are looking for, the first three options do not support the idea of success in reproduction.
