VLS_GUY":1j2vgtol said:The University of Alberta had double muscled purebred Angus cattle in the mid 1960's before Limos were imported. I also remember seeing pictures of double muscled Angus in text books from the same period. This is not to say the bull pictured doesn't have some limo in him but it isn't a slam dunk. ABS in the UK sells semen on the pictured bull Oakchurch Dictator. He is out of a Canadian bull Dalrene Cruz (heavy muscled).
The myostatin gene shows alot of polymorphism though out all breeds. Check it out at: http://www.biomedcentral.com/content/pd ... -1-103.pdf. Note the likely source of disruptive haplotypes is the Frisian not the Shorthorn. Perhaps the double haplotypes came from the Holstein breed for the pictured bull. Also the influence of other loci must be considered to explain variability in populations with fixed disruptive haplotypes.

Why wouldn't a commercial cattlemen raising cattle for beef not want to breed his cows to a bull that carries two copies of the myostatin gene?
Would this not produce an offspring that will have the optimal carcass hanging on the rail?
Yes many 4H projects don't do well in the ring but kick butt on the rail. Great question!! No great answer available, prejudice and predisposed opinions are hard to break thru. :2cents: Progress is being made but slow.Jovid":2a56otpt said:So the question is:
