If the altitude of your equilateral triangle is one, the genotype frequencies P1, P12, and P22 are simply the perpendicular distances from a point to the sides of the trian- gle, with P11+P12 + P 22 = 1. Prove that a vertical line from a point in your triangle will divide the base of the triangle in the ratio p to q, where p and q are A, and A, allele frequencies.
