Vinca (the periwinkle family) have a height determined by polygenes. The shortest Vinca grow to a full height of only 3 inches, whereas the largest Vinca is 21 inches high at maturity. If one crosses a 3-inch Vinca and a 21-inch Vinca, 12-inch Vinca result. If the F1 are allowed to interbreed, then one gets a range of plants from 3 inches to 21 inches high. However, one only obtains about eight plants in 512 that are 3 inches high and only about eight plants in 512 that are 21 inches high. What is the contribution per contributing allele? If two 12-inch (F1) Vincas are crossed, what is the probability of observing a 6-inch Vinca? If a 12-inch F1 plant is crossed to a 21-inch plant, what is the probability of observing a 15-inch plant?
