I second what TCF said. From a breeding standpoint all clones are genetically the same. The only difference would be some mitochondrial DNA difference from the clone and the original, but that is due to residual mitochondrial DNA in the host embryo and will not be passed along in the sperm cell. Any physical difference you see between the original and clone is going to be because of environment and how they were raised. Difference in calves out of them is going to be due to cows they were bred to, environment, and how they were raised also. Genetically they are all the same!
