WebTypes of genetic mutations include: Germline mutation: A change in a gene that occurs in a parent’s reproductive cells (egg or sperm) that affects the genetic makeup of their child (hereditary). Somatic mutation: A change in a gene that occurs after conception in the developing embryo that may become a baby. WebJul 4, 2024 · These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection (previously discussed here). Each mechanism of evolution can be characterized by how it affects fitness, adaptation, the average phenotype of a trait in a population, and the genetic diversity of the population.

WebSomatic evolution is the accumulation of mutations and epimutations in somatic cells (the cells of a body, as opposed to germ plasm and stem cells) during a lifetime, and the effects of those mutations and epimutations on the fitness of those cells. This evolutionary process has first been shown by the studies of Bert Vogelstein in colon cancer.
