Is color pased on via male sheep?

Like with all animals, both mom and dad play a part in determining the color of the offspring. Geneotype (the internal code) and Phenotype (what they look like outwardly) both come into play when breeding for color. Therefore it is best to know parentage for both mom and dad, if you are trying to breed for color or pattern. Dad may be all white but he comes from a long line of spots and blacks, etc.
