Blog #4 (Selection)

Blog # 4 Describe the three types of selection: directional, stabilizing and disruptive and give an example of each.




Directional:a pathway of natural selection in which one uncommon phenotype is selected over a more common phenotype. An example would be Breeding
Stabilizing:a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value. An example of this would be human baby birth weight 
Disruptive describes changes in population genetics in which extreme values for a trait are favored over intermediate values. An example would be Rabbits
