Albino cats are born with a missing or damaged TYR gene. So they don’t have the enzyme Tyrosinase, which is needed to produce melanin. The white cats come in several types. eg DW (Dominant White), Ws (White spotting) etc. It's the KIT gene that determines the variant. They all are are alleles of the same KIT gene. A dominant white gene simply overrides other colours. White cats with blue-eyes are often, but not always, deaf and light-sensitive. If a white cat has one blue and one orange eye, the cat may be deaf on the side with the blue eye.Burmese or Siamese cats, have a different recessive tyrosinase gene called temperature sensitive albinism. (also present in the Himalayan mouse)Note - Cats have 38 chromosomes (Humans have 46, which is often referred to as 23 pairs) Genetics works the same across the species and recent Zoonomia Project analyzes the DNA of the mammalians.</blockquote>
