[QUOTE="Jeanne - Simme Valley, post: 1490920, member: 968"] We will agree to disagree. ASA did a lot of DNA testing on black bulls, coming up with my quote of "unmeasurable" other breeds. There are a lot of up-grading now. 1/2 bloods have gotten extremely popular - as cows and as bulls - and as feedlot cattle. But, no matter how you figure it, 4/8 to 7/8 = 5.5/8 (called 3/4). 5.5/8 x 7/8 = 6.25/8 (called 7/8) So, you would have to use % bulls for many years to creep up (or down) to 75%. [/QUOTE]
