Abstract

At least 260 v isib le tra its of cattle, excluding coat colors and patterns, have been reported to be under control of major genes. While some o f these tra its resemble others in certain anatomical, physiological, or pathological features, dissim ilarities among them, including their occurrence in separate breeds o f ca ttle, argue for control by separate lo ci. Despite the scanty evidence available for some loci, visib le tra it loci collectively represent the largest group known in cattle. Only a few have been assigned gene symbols, usually as examples in textbooks.
