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:
- <em>A trait that can be inherited from one generation to another.
</em>
- <em>The trait is subject to variability between subjects of the same species.
</em>
- <em>Genetic variability can determine the possibility of reproductive success and survival.
</em>
Therefore, <u>a necessary factor for natural selection to occur is that genetic variability exists in the population</u>.
