Question

Mutation is an important mechanism for evolutionary change.

Which type of mutations contribute to evolution?

Germinal mutations
Somatic mutations
Both somatic and germinal mutations

Answer 1

The answer is Germinal mutation.

Step-by-step explanation:

In Eukaryotes we find two types of cells, one is somatic cell or vegetative cell and the other is germ cell. If the mutation occurs in germ cell then it is inherited to the next generation because germ cells give rise to gametes which fuse with other gamete during mating. So only such mutations can cause evolutionary change. If the mutation occurs in somatic cell, its not inherited and thus plays no role in evolution. Mutations occurring in germ cells are called germ-line mutation or germinal mutation.

Answer 2

Somatic mutation is the type of mutation among the choices given in the question that contribute to evolution. The correct option among all the options that are given in the question is the second option or the penultimate option. I hope that this is the answer that has actually come to your desired help.
