In a study of flower color in a population of true-breeding red-flowered and white-flowered plants, the red color is dominant, and white is recessive. Crossing true-breeding red-flowered plants with true-breeding white-flowered plants results in an F1 generation where 100% of the offspring have red flowers. The F1 plants are self-fertilized to produce an F2 generation. In a randomly selected set of 100 flowers from the F2 generation, you observe 75 red-flowered plants and 25 white-flowered plants. What is the observed frequency of the dominant allele in this F2 population? Select the right answer and show your work on your scratch paper for full credit.
