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? Explain your answer.

Answer 1

Random mutation

Gene deletion

you can google these definitions, so these are two ways

Answer 2

I agree with mutation, but I think that gene flow from another population would be a likely source of variation.

Answer 3

sexual reproduction would result in gene mutations, or they could mate with a different species that it was reproductively possible to mate with, which would introduce more genetic diversity
