Document Summary
Insert wild fw2. 2 allele into 1 fruit = 30% reduction in size. Large fruits were at first rare mutations, but with years of artificial selection, farmers eventually eliminated small-fruited alleles from their stocks. Individuals within populations are variable: the variations among individuals are, at least in part, passed from parents to off-springs, the survival and reproduction of individuals are not random; instead they are tied to the variation. In every generation, some individuals are more successful at surviving and reproducing than others among individuals. The individuals with the most favorable variations, those who are better at surviving and reproducing, are naturally selected. Mild chili are eaten by packrats natural selection of hot chili. Hiv and the ability of the reverse transcriptase to bind azt. Each theory of the 4 postulates are testable. Darwinian fitness: the ability of an individual to survive and reproduce in its environment.
