Answer:
Increase in frequency.
Explanation:
The theory of natural selection states that genetic variations are present in the natural populations. Some organisms have one or more genetic variations which in turn increase their chances of survival and enable them to reproduce more. These organisms leave more progeny. It results in an increase in the frequency of those beneficial genetic variations in the population over the generations. This is how natural selection favors adaptive genetic traits and increase their frequency in the populations.
