WebThe purpose of this study was to build upon previous genetic studies by examining the genotypic variation in ASD and its relationship to parental age and phenotype. In particular, this study examined the hypothesis that genetic mutations in individuals diagnosed with ASD are important to phenotypic variation. Methods WebPhenotypic variation is the changeability in aggregates that exists in a population. Overview of Genetic And Phenotypic Variation Genetic variation can be recognized at numerous levels. Genetic variation can be identified by analyzing variation at the degree of compounds by the use of the cycle of protein electrophoresis. sleep lab owensboro health https://ambertownsendpresents.com

Phenotypic variation (due to underlying heritable genetic variation) is a fundamental prerequisite for evolution by natural selection. It is the living organism as a whole that contributes (or not) to the next generation, so natural selection affects the genetic structure of a population indirectly via the contribution of phenotypes. Without phenotypic variation, there would be no evolution by natural selection.
