n a fox ranch in Scandinavia, a mutation arose that yielded a “platinum” coat color. The platinum color proved very popular in the fox coat trade, but, in spite of enormous effort on the part of fox breeders, a pure- breeding platinum strain was never achieved. Every time that two platinum fox were crossed, some wild-type offspring appeared in the progeny. For example, the repeated crosses of a single pair of platinum fox produced 83 platinum and 38 wild-type progeny. All other such crosses gave similar progeny ratios. State the genetic hypothesis that accounts for these results.
