A horse breeder for the Kentucky Derby recently noticed that one of his  female horses gave birth to an offspring, a daughter horse, that had  several desirable traits to be a successful racing horse. The offspring had  a well-chiseled head on a long neck, high withers, a deep chest, a short  back, good depth of hindquarters, a lean body, and long legs. The farmer  would like to identify which male horse is the offspring’s father for  selective breeding purposes. He asks a local university to run a DNA  fingerprint with DNA samples from the mother, offspring, and the four  male horses on the farm.
