Question

Mutation leads to evolution and speciation.

• A. True
• B. False

Answer 1

The correct option is A

True

Mutations are sudden and heritable change in the genetic constitution of an organism. This may occur due to the defects in the duplication of DNA, certain chemicals, radiations etc. The effects of certain mutations are visible immediately while some are expressed after many generations.
Nature selects the beneficial mutations and eliminates the lethal ones. These sudden heritable changes get accumulated over the years and eventually, resulting in evolution and speciation.
