MUTATIONS.
What is mutations?
Mutations are sudden changes in the genotype that are inherited.
Mutations are rare in nature and mutated genes are usually recessive to the normal (wild type) genes.
Most mutations are generally harmful and some are lethal.
A somatic mutation is a genetic change in somatic cells.
Somatic mutations are only inherited if asexual reproduction takes place e.g. as in plants and unicellular animals.
