Question

Variations in genetic information is key to evolution. Which of the following is the means for creating new alleles

A. gene flow

B. genetic drift

C. Mutations

D. Natural selection

Answer 1

Ans: Mutations

Explanation: Genetic variation in evolution allows natural selection to alter frequency of alleles already in the population

mutations creates new genes and alleles and this increases genetic variation.These variations often alters gene activity , which can introduce different traits in an organism ,If a trait is advantageous and helps the individual survive and reproduce, the variation will be passed to the next generation through natural selection, the passed variation will dominate the population and give rise to a new species.Only mutations In gametes can lead to evolution ,because they are passed to the next generation.It is important to note that not all mutations are beneficial or advantageous , some leads to harmful traits.
