40%
50%

10%
Hint:
40%
The correct answer is: 40%
Researchers found that only 17 to 22 percent of white cats with non-blue eyes are born deaf. The percentage rises to 40 percent if the cat has one blue eye, while upwards of 65 to 85 percent of all-white cats with both eyes blue are deaf. Some of these cats are deaf in only one ear. If a white cat with one blue eye is deaf in only one ear, that ear will invariably be on the same side of the head as the blue eye.
