Each parent randomly passes one of it's horn genes to the calf. If the animal, sire or dam has two horn genes it will horned and always pass one horn gene. If it is polled, it may be homozygous polled, two polled genes and will alwasy pass one polled gene, the off-spring will be polled. If it is heterozygous polled, one horn gene and one polled gene it may pass either. If it passes a polled gene the calf will be polled, if it passes a horned gene and the calf receives a horned gene from the other parent it will be horned.
