What is mutation in genetics?

A mutation in genetics is a sudden and permanent change in the DNA sequence or genetic material of an organism.

Mutations can occur naturally during DNA replication or may be caused by external factors such as radiation, chemicals, or environmental changes.

These changes can affect a single gene, a part of a chromosome, or even the entire chromosome structure. Some mutations may have no effect, while others can lead to new traits, genetic disorders, or variations in organisms.

For example, certain mutations can change eye color, affect body functions, or increase resistance to diseases.

Mutations are important in genetics and evolution because they create genetic variation, which helps species adapt and evolve over time.
