I like Schaff bulls and have used a couple and yes, the paper trail follows them here to Australia, especially their marbling. I can't fathom why, I do not think that progeny of Schaff bulls would average any less with marbling hanging on the rail than any other lines. Is it that they don't bring in a lot of outside genetics? When they do they don't necessarily select for that trait. When they submit scanning data there is not a lot of outside genetics for the data to be compared to????

"More specific to this discussion is the genetic correlation between ribeye area and
marbling (-.21) and that between marbling and yearling weight (-.33). Although both pairs of
the above traits would be desirable, the unfavorable genetic correlation will slow response to
selection for both traits in each pair."
