Blog 4: Types of Selection

• Directional Selection: This selection is when an uncommon phenotype is chosen over a more common one. It will change the allele frequency by shifting it to another direction, eventually becoming fixed.

• Stabilizing Selection: This selection is when genetic diversity dwindles as population goes stable on a trait value. One of the most common form of natural selection, it mostly leads to negative selection. 

• Disruptive Selection: This selection is when extreme values for a trait is chosen over more plain values. Due to varying traits, it'll eventually lead to two distinct groups of the same organism.
