General informationThis section has been translated automatically.

A mutation is a permanent change in the genetic material. The following types of mutations are distinguished: gene mutation , chromosome mutation , genome mutation. Mutations can occur spontaneously e.g. during DNA replication or meiosis. Mutation can also be induced e.g. by mutagens. Induced mutation: Factors outside the cell (mutagens), can also cause mutations. These are, for example, high-energy radiation, such as X-rays or UV radiation, as well as certain chemical compounds or special viruses. The following inheritance patterns are known:

  • Somatic mutation (confined to body cells only).
  • Germline mutations (the mutation is passed on to offspring).

The following forms of mutations are distinguished:0
