[QUOTE="Son of Butch, post: 1466161, member: 14585"] Milk is by far the least heritable trait at .12 (12%) (from angus assoc website) breed average for milk is 24 and 12% of average would be a change of plus or minus 3 Scrotal is tied for 2nd highest heritable trait along with marbling at .48 .... both behind stature... yh .51 mh .62 Scrotal is much easier to change than milk in one generation.... my guesstimate would be a 20 percentile change could be made in one generation. ie offspring of a breed average animal could swing up to top 30% or drop to bottom 70% in one generation for scrotal [/QUOTE]
