WebGenetic Variation Mutation; 1. Genetic Variation leads to changes in the allele or gene frequencies in a population. Mutation causes a permanent change in the genetic sequence of an organism. 2. Genetic variation can occur due to mutation, reproduction, genetic drift, gene flow, environmental factors, natural selection, etc. WebNote: In many places, the term “mutation” is used in reference to a genetic change that causes disease, and therefore has a negative connotation. However, a mutation does not necessarily cause any disease or is pathogenic, and can be neutral or even benign. The current guidelines for interpreting changes in DNA sequences (see Richards 2015, …
