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 … See more 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. The term covers the organism's See more Despite its seemingly straightforward definition, the concept of the phenotype has hidden subtleties.
