[QUOTE="Ebenezer, post: 1781644, member: 24565"] Good question. The isolated genepools in wild populations might have increased inbreeding but little crossover of a few males siring offspring in the whole population. Bottlenecks can occur in breeds or groups via either too few males, too few females or overuse of the same males in the entire population. There is strength in the isolated or separated genepools via mere distance, natural barriers, distances that males are willing to travel. When individuals of the same species or breed from separate isolated genepools mate, the reshuffling of the genes is a refreshing back towards original vigor. As in Angus, the salivating of a lot of folks to use some of the same "top bulls" each year from the same sources or with some similarity of genetic backgrounds is the point of concern. Not as bad as Holsteins, but headed that way. Funny, EPDs have been used for decades and folks still have to go out and find breeders in other herds to keep up. Makes me wonder about the validity of EPDs to be honest. [/QUOTE]
