WebGenetic drift affects the genetic makeup of the population, but unlike natural selection, through an entirely random process. So although genetic drift is a mechanism of evolution, it doesn’t work to produce adaptations. More Details Teaching Resources Read more about: The mechanism of genetic drift, sampling error The effects of genetic drift WebEach of these four processes is a basic mechanism of evolutionary change and is illustrated with an example of gene frequency change in a beetle population with brown and green individuals. Mutation: A mutation could cause beetle parents with genes for bright green coloration to have offspring with a gene for brown coloration. That would make genes for
