[QUOTE="Ky hills, post: 1830086, member: 24816"] I appreciate your response and take on this. I agree heterosis and consistency don't seem to come together logically. This is how I see both concepts working. Take for example a herd of Angus cows bred to a Charolais bull. The resulting calves will have sone variation but all will look like similar Charolais cross calves the real variation in phenotype between the parents will likely show up more pronounced later in life. Same with a crossbred herd of cows and a Charolais bull, the calves will be identified as CharolaisX. I mention in response another comment about the variation with breeds, and I referenced the Angus bulls Coleman Charlo and Sydgen CC&7, two very different bulls but I believe the latter to be more of an outlier and his calves could have quite a bit of variation as well as far as performance if they skew more towards breed average. I agree that crossbreeding has made sense financially to several breed associations. I believe that SimAngus helped to open back the door for more of a market for purebred Simmentals in recent years. I also agree that all crossbred animals are not inferior to purebred. I would rather have a good quality sensible crossbred bull than a poor quality purebred, If money and quality were equal I’d personally choose a purebred unless as you mentioned it was a situation where the crossbred might work better for a specific purpose.
