On the Indonesian island of Bali, about 3/4 of the feral (stray) cats have a stumpy tail while only 1/4 of the cats have a regular long tail.

You did the same with the the regular tailed cats, but they always had only regular tailed kittens. What does this tell you about the genotype of the regular tailed cats
