Solve the problem.Mendel found that flower color in certain pea plants obeyed this scheme: Pure red crossed with pure white produces red. When pure red (RR) and pure white (rr) parents are crossed, the resulting Rr combination (one of each gene) produces second generation offspring with red flowers, since red is dominant. Suppose that two of these second generation Rr flowers are crossed. What is the probability that the resulting plant will have red flowers?
