Web2 de sept. de 2024 · Natural Selection as the Mechanism of Evolution Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. Two of the basic assumptions of natural selection are that variation in a trait is possible, and that a given expression of a trait is able to be inherited. WebNatural selection operates on phenotype. Unequal mortality or reduced reproductive success across populations are associated with variation in phenotypes. It is the …

WebNatural selection acts on an organism's phenotype, or physical characteristics. Phenotype is determined by an organism's genetic make-up (genotype) and the environment in which the organism lives. When different organisms in a population possess different versions of a gene for a certain trait, each of these versions is known as an allele. WebAlthough natural selection acts on physical traits, or phenotypes, these characteristics must also be controlled by genes so that they are heritable and can be passed from one generation to the next. ...
