Exactly. It's like mixing dog breeds. German Shepherds and Cocker Spaniels are both beautiful dog breeds. If they procreate, their offspring may not be very beautiful.
A dog's breed contains 1,000s of years of artificial selection, optimizing for certain traits. If you mix dog breeds, you may get a dog that has neither the optimized traits of the mother nor the optimized traits of the father. Of course, there's also hybrid vigor. Sometimes, genetic experiments work amazingly well.
