Answer: 0% will have short hair.

Explanation: Because both breeds are purebred, (homogeneous), their offspring will all be heterogeneous. In this case, all the offspring will be heterogeneous dominant, which means all of the cats will have short hair, leaving none with long hair unless a long-haired cat is crossed with a one of the heterogeneous dominant cats in the F2 generation.
