natural selection

process by which organism that are most suited to their environment survive and reproduce



stabilizing selection


directional selection


disruptive selection

individuals near the center of the distrubution curve have higher fitness


- causing allele to shift over direction, changes


-changes in population genetics with extreme values for traits
