What is mutation? Explain its significance.

Mutation is a sudden and permanent change in the genetic material (DNA) of an organism, which can alter a gene or chromosome.

Mutations can occur naturally due to errors during DNA replication or be induced by external factors such as radiation, chemicals, or environmental influences.

They can be beneficial, harmful, or neutral. Beneficial mutations may provide advantages such as better adaptation to the environment, while harmful mutations can lead to genetic disorders or diseases. Neutral mutations may have no noticeable effect.

Mutations are significant because they introduce new genetic variations in a population. These variations are essential for evolution, as they provide raw material for natural selection.

In some cases, mutations have led to the development of useful traits in organisms, contributing to biodiversity.

Thus, mutation is an important biological process that drives variation, evolution, and genetic diversity.
