WebNatural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits. For example, some beetles are green and some are WebGenetic drift occurs because the alleles in an offspring generation are a random sample of the alleles in the parent generation. Alleles may or may not make it into the next … WebVariation in a population can be influenced by mutation rate, genetic drift, sexual reproduction, meiosis and gene flow. Variation is important for adaptation and evolution. Evolution begins with the inheritance of new genetic variation. Variation describes differences in the genetic make-up between individuals within a species. the priory - highbank centre
