I truly doubt this. From my experience breeding cattle, given one subject with white skin would not result in a white race. The dark skin would dilute the genes and subvert the white with the dark skin remaining dominant.

In other words, one white cow in a herd of black cows will not get you a white herd. One white bull in a black herd, breeding back to his daughters could lighten the herd if the breeding pool were kept small and selective but in an open situation like range cattle (free running humans) The white would disappear.

I thought hair, not skin gives the colour and patterns to cows and bulls.

Cold climes produce ongoing selection.

Do you think that animals in the wild select mates based on appearance?
