Question

Mutations are important for evolution because they _____.

are the source of new genetic variation


improve the survival of organisms


remove excessive genetic variation


allow individual organisms to evolve


Description

Answer 1

The more mutation the more new variety of gene combination will exist contributing to diversity

Answer 2

The answer is they are the source of new genetic variation.

Step-by-step explanation:

According to the U.S. National Library of Medicine, genetic variations can arise from gene mutations or from genetic recombination. It is also mentioned that these variations can alter gene activity or protein function, introducing this way different traits in an organism. So, if this trait has good results, it most likely will be shown in the next generation. This process is known as natural selection.
