i agree we can't put full faith yet in the markers as well. Jimmyski, were all the progeny tenderness tested that were slaughtered and equal star individuals compared on any basis? for instance, you could have one bull by chance passing on more of the T2 marker (the rarest by the way), and depending on the background of each of the two cow herds, you could have some differences there as well. for instance, if the above bulls were crossed on cows that had 0 stars, the offspring could only have a maximum of 2 stars, each one in a different gene. what other bulls were in the test that had less stars, but in the offsrping had both more and less stars and was this inconsistent as well? of course one would like to match equally starred bulls with equally starred females, obtain equally starred offspring and then measure all carcasses. was any of this done? is there a power point link to the presentation? i have a couple of queries to bovigen to address teh marshall/abs study as well as the marker not in common with ingenity.

knabe,
You might try and contact Lorna directly as I can not remember the exact accounts of the study that she presented. I know the bulls own personal genotype was 2-1-2, but could not tell you the official results of what the cows and progeny were. I would suspect that she probably has this information available if you were to contact her directly.
