Question

Variation in a trait is a required condition for natural selection to act on a population for that trait. Assuming a population of organisms only started with only one form of a trait, what are two ways variation in the trait could be introduced into the population?

Answer 1

I) Sexual reproduction

II) Mutation

Step-by-step explanation:

Variations refer to the difference observed within organisms of the same species. Variation are introduced into a population by:

- new genetic combinations that occur during sexual reproduction (i.e during meiosis)

- mutations, spontaneous changes that occur in genes and chromosomes.
