You are studying a variety of pea plant that has either red flowers or white flowers. When you cross true-breeding red-flowering plants with true-breeding white-flowering plants, you get all red-flowering plants in the F1 generation. If you then allow the F1 plants to self-ferilize, you observe that 75% of the F2 plants are red-flowering plants, while 25% of the F2 plants are white-flowering plants. Next you make 640 different monohybrid crosses and decide to analyze only the first 8 plants produced from each of these crosses (i. e. a total of 5120 progeny plants total). How many of these crosses would be expected to produce 6 red plants and 2 white plants?
