Genetics and Colours - as promised

Hreow · 30-03-2006, 02:01 PM

The eye-colour is apparently not a single-gene thing, so you could have a wide range of colours. Blue in white cats has something to do with the whiteness, but (as far as my books tell me) that's about all the certainty you get.

I imagine the pedigrees would have been bred from breed-standard eye-colours - thus making sure that that complex of eye-colour related genes is more present in the stock? I.e. Abys are most likely to have yellow/amber eyes, with an occasional green, because anything else wasn't given a chance to breed.

White cats with blue eyes are also frequently deaf, if I recall correctly.

aaaah ok, so tortie is more patches, tabby more stripey.

Getting there, albeit rather slowly!

what on earth has poor kay let herself in for?

But there is a stripey tortie-type as well.... Argh!

Snoof: Cats with different coloured eyes and white are apparently even supposed to be predominantly deaf on the blue-eyed side.

That article was great thanks, Snoof - it help me understand more about my tabby boys.

However, on a different thread (the red tabby thread I believe) I'm sure someone said there is no such thing as a black tabby? In that article it says the black and agouti tabby is called brown in the US and black in the UK - and now I'm confused again!

i think blue eyes have to be carried by both sire and dam so if you breed a blue eyed ragdoll (all ragdolls have blue eyes) to a moggie then the kittens would not have blue eyes
do all colour pointed cats have blue eyes?
