[QUOTE="VanC, post: 660057, member: 3355"] As has been said already, you don't multiply the percentages, you ADD them and divide by 2. Let's say you breed a bull that's 87% Angus and 13% Gelbvieh to a cow that's 87% Angus and 13% Gelbvieh. Using your method of 87% x 87%, the offspring is 75.69% Angus. But you also have to multiply the 13% x 13%, which results in a calf that's only 1.69% Gelbvieh. That leaves a total of 77.38%. What happened to the other 22.62%? To take it a step further, if you keep using your method, after 6 or 7 generations you'll have an animal that has virtually no Angus OR Gelbvieh blood. Without bringing another breed into the mix, I'll go out on a limb and say that's impossible. As Knersie said, your math is right, but your application is wrong. [/QUOTE]
