In a new strain of dog, you find two new recessive mutations. One mutation results in the animal having a short tail (st), and the other mutation causes the dog to be spotted instead of a solid color (po). After more study, you discover that the two genes for the traits are 22 mu apart. If you mate individuals heterozygous for both traits (st + / + po), what percentage of their offspring will be both short-tailed and spotted, assuming no double crossovers?
