Phenotypic variations meaning
WebThe meaning of PHENOTYPE is the observable characteristics or traits of an organism that are produced by the interaction of the genotype and the environment : the physical … 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 … Zobraziť viac In genetics, the phenotype (from Ancient Greek φαίνω (phaínō) 'to appear, show, shine', and τύπος (túpos) 'mark, type') is the set of observable characteristics or traits of an organism.
