Crossing true-breeding pea plants with yellow peas with true-breeding plants with green peas yielded an F1 generation with 100% offspring plants with yellow peas. The F1 plants are self-fertilized and produce F2. In a randomly selected set of 100 peas from F2 you notice the following phenotypic numbers: 84 yellow and 16 green.  What is the observed frequency of the dominant allele in this F2 population?
