Modes of selection: directional, balancing and disruptive RR Rr rr
... Directional selection replaces one allele with another (fitter) allele. At equilibrium the population is monomorphic (fixed) for the fittest allele. Balancing selection prevents the loss of two or more alleles at a locus, by increasing the marginal fitness of each allele as it becomes rarer. There a ...

NOTES: Natural Selection
... If the environment stays the same, then natural selection favors organisms with certain adaptations. Organisms with these adaptations (traits) survive and reproduce. Organisms that do not possess these traits may not survive long enough to reproduce. The population adjusts to the environment o ...
