[QUOTE="Jeanne - Simme Valley, post: 1517174, member: 968"] Yes, it is a dominant trait in the female. It would not show up to 25% in his granddaughters, if the daughter was bred to a non-scurred bull - 0 would be scurred. A scurred cow bred to a bull with 0 scur gene will produce a daughter that is not scurred (but will carry 1 scur gene). If the bull has scurs bred to your scurred cow, all your male calves will be scurred - simply from the dam, even if the bull was clean polled. ALL her male calves will be scurred (1 scur gene). Maybe 50% of her heifers will be scurred (two scur genes), if you used a scurred bull (1 scur gene). 0% daughters will be scurred if you use a clean polled bull with your scurred cow. This is not new, been the same genetics for ever. Pretty simple. [/QUOTE]
