Answer:
For natural selection to occur, it is true that there must be genetic variation in the population.
Explanation:
According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.
For natural selection to occur, three fundamental conditions must exist:
A trait that can be inherited from one generation to another.
The trait is subject to variability between subjects of the same species.
Genetic variability can determine the possibility of reproductive success and survival.
Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.
