DIAGRAMMATIC ILLUSTRATION OF THE INHERITANCE OF HORNS IN CATTLE

If a bull that is pure or homozygous for the polled character is mated with a number of horned females, all of the calves will be polled; whereas if a bull that is impure or heterozygous for the polled character is mated with a number of horned females, only half of the calves will, on the average, be polled.
