[QUOTE="Brandonm22, post: 615737, member: 7645"] I think if you combine EPD chasing with heavy AI use breed wide, it definitely decreases genetic diversity. I don't have the data to prove it but I bet Angus had more genetic diversity 30 years ago (when they were a smaller breed) than they do now. People start chasing multiple EPDs on the outer 5% of the bell curve and invariably there aren't that many unrelated AI sires out there on that cutting edge. I am not saying that is ALL bad; but it does tremendously magnify the role that a handful of bulls play at the cost of numerous other sires. [/QUOTE]
