Crоssing true-breeding peа plаnts with yellоw peаs with true-breeding plants with green peas yielded an F1 generatiоn 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 recessive allele in this F2 population? Select the right answer and show your work on your scratch paper for credit.
