I know of a cow that smokes the odds... Double Stuff x WMW blue roan, but not really a blue roan.. she's got some color on the head and underline, and 4 socks.. think maybe even a white switch. Anyways, bred her two years in a row to black bulls... the first a maine, the second a sim... guess both bulls were hetro black, cuz both years that cow cranked out red roan heifer calves... I'm guessing she bred on the roan, and since both bulls were red carriers, they bred on the red... any other explanations?
