WebHow does genetic variation occur in meiosis? There are three ways that the cells produced in meiosis are different from each other and from the parent cells:1) Independent assortment: this is the idea that during metaphase 1 and 2 pairs of homologous chromosomes randomly line up. 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.
