1. Compare directional selection and disruptive selection, Provide an example of each. The two different types of selection differ because instead of the subject only going in one direction it will split off and go two different ways. This would be disruptive selection where there is more than one option to select or two distinct groups.

A population of deer has legs of The disruptive selection definition is defined as an evolutionary force that drives a population apart. The disruptive selection causes the organisms with intermediate traits in order to reproduce less, and allow those organisms with extreme traits to produce more. This fact causes the alleles for the extreme traits to increase the frequency.
