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.
