Do White Cats With Blue Eyes Deaf
Cornell University cites a study that found that 17 to 22 percent of white cats with non-blue eyes were born deaf.
Do white cats with blue eyes deaf. About half of all white cats are deaf and those numbers increase in cats with blue eyes with deafness often found on the same side as the blue eye left blue eye deaf in left ear. The blue eyes and white coat are a result of a lack of melanin in pigment cells. Overall statistics indicate that.
Black and white cats with blue eyes have a much more common type of hearing and vision problem that may be. Dominant epistatic white is a masking gene that overrides all other coat colours and is symbolised with the letters W D. Not all blue-eyed whites will be deaf since there are several different genes causing the same physical attributes whiteness blue-eyedness so it all depends on the cats genotype its genetic make-up not its phenotype its physical appearance.
For those cats with other colored eyes only 10-20 are deaf. Do all white cats with blue eyes are deaf. An estimated 40 percent of white cats with blue eyes are deaf which is high.
The variable penetrance of deafness and eye colour may be caused by interplay with other genes andor environmental factors. White color of the coat occurs in cats. As we have mentioned previously not all white cats with blue eyes are prone to deafness.
Reports of this condition date back to at least the 1930s Bamber 1933 and many investigators have studied it in. These animals are well-known to be commonly affected by a congenital hereditary deaf-ness that may affect one or both ears. When one or both eyes are blue anywhere from 60 to 80 of white cats will be 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. The deafness is linked to the so-called W gene. First of all it can be said that not all white cats are deaf but they are more likely to be deaf since they carry the so-called gene W White of white in English especially those that have one eye of each color or blue eyes.
