What are some common types of genetic mutations?

Common types include point mutations, insertions, deletions, and duplications. Each type can have different effects on the organism.

Can genetic mutations be beneficial?

Yes, some mutations can be beneficial, providing advantages like increased resistance to diseases or better adaptation to environments.

How do genetic mutations relate to evolution?

Genetic mutations are a primary source of genetic variation, which is essential for natural selection and evolution.

Are all genetic mutations harmful?

Not all mutations are harmful; many are neutral or beneficial. However, some can lead to genetic disorders or diseases.
