14.12 Snap Peas Suppose you are interested in following two independent traits in snap peas-seed texture (S smooth, s wrinkled) and seed colour (Y yellow, y green)-in a second-generation cross of heterozygous parents. Mendelian theory states that the number of peas classified as smooth and yellow, wrinkled and yellow, smooth and green, and wrinkled and green should be in the ratio 9:3:3:1. Suppose that 100 randomly selected snap peas have 56, 19, 17, and 8 in these respective categories. Do these data indicate that the 9:3:3:1 model is correct? Test using a = 0.01.
