WebFrom the Punnett square, Mendel predicted that the offspring of the cross would have a phenotypic ratio of tall to short plants of 3 : 1.. G.H. Hardy, a British mathematician, and W. Weinberg, a German physician, realized that they could apply a similar approach to predicting the outcome of random mating, not just for an individual cross but for crosses … WebExplain what it means for a 9:3:3:1 ratio to be two 3:1 ratios combined at random. Use a branch diagram to illustrate this concept. A 9:3:3:1 ratio results from a self-cross of a heterozygous parent. When focusing on one gene from this parent, it will have a 3:1 ratio in the next generation (Y/y self cross will result in a 3:1 yellow:green ratio).
