How do gene mutations contribute to evolution?
|
|
Beneficial mutations are passed on to several members of a generation, quickly taking hold in a population.
|
|
|
Unfavorable mutations have a more significant effect on genes than do favorable mutations, so they are spread through the population.
|
|
|
Natural selection favors beneficial mutations, so they survive and are passed on to future generations.
|
|
|
Beneficial and unfavorable mutations take hold in the population equally over numerous generations.

Explanation:
Detailed explanation-1: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
Detailed explanation-2: -How does natural selection work? In natural selection, genetic mutations that are beneficial to an individual’s survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce.
