2. In another population of morning glories, there are 500 plants and 5 of them have white flowers. It is also known that mating was random with respect to flower color in the previous generation. (a) What is the frequency of allele A1? (b) How many red-flowered plants are there?

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
