[QUOTE="redcowsrule33, post: 1530708, member: 8629"] The roaning gene is an odd one. Technically a recessive trait but is expressed differently based on whether or not the animal is heterozygous or homozygous. No roaning gene = solid color One roaning gene (hetero) = roan Two roaning genes (homo) = white If the cow is a roan she is heterozygous and her calves have a 50:50 chance of being roan as long as the sire does not carry the gene. Spotting genes will not affect the expression. [/QUOTE]
