[QUOTE="dph, post: 363778, member: 2112"] Brandon, I don't believe either thing you stated is entirely correct. You are looking at it from top down, and the way it appears they are working it is from bottom up. Once they have isolated a gene they believe to be responsible for tenderness, all the need to do is compare a population of cattle with it to those without it. Which they have done. It doesn't matter what bulls they are out of as long as it impacts tenderness in the general environment that I raise my calves in. Once they prove a number of genes that affect tenderness significantly, it matters whether that bull has it or not. Second, the packer won't DNA test the calves before slaughter. They are already developing several tests, such as the IR scan discussed in another topic, that will not slow the line up. This eliminates verification needing to be based on DNA or how they were bred and then worrying on whether the genes were passed down or not. All anyone is really concerned with is end result, whether you got their by chance or planning shouldn't be an issue to them as long as its tender. It should be an issue to the producer though. With tenderness, all I want to do as a commerical producer is increase the odds significantly that my calves will qualify for being tender, which I can do by studying the genes that I introduce in my herd through our bulls, without compromising other EPDs or performance or confirmation. Increase the population of the genes in my herd over time and increase the likelihood that my calves will inherit them. [/QUOTE]
