Information about the Hardy Weinberg equation: http://www.nature.com/scitable/definition/hardy-weinberg-equation-299

The Hardy Weinberg equation is a very important concept in population genetics. Suppose we have two "alleles" for a specific trait (like eye color, gender, etc..) The proportion for which allele is present is given by and

Then by Hardy-Weinberg:

, where both and are non-negative.

Which statement discribes the graph that would appropriately represents the above relation?

Answer

As a simple test, all other values when substituted into the original equation fail. However, works. Therefore is our answer.
