i am currently helping to determine a fellow breeders kitten........i say help but really mean im confused! lol doesnt take much i must admit. i am up to speed with the 'normal' red's, black tortie's, tabbies, dilutes ect. BUT! my friend has a chocolate tortie whom he bred to a solid choclate boy. now im not one to question that his pedigree is wrong, and in fact his cat is a black tabby {she's a sphynx so harder to determine than a coated cat} could anyone give me the possible kitten colours from this mating? im yet to find out if she and the boy carry for dilute or pointed, but can work that part out......hopefully!!! thanks in advance!!!!!

chocolate to chocolate tortie =
girls - chocolate or chocolate tortie
boys - chocolate or red

if both carry dilute then
girls - chocolate, lilac, choctortie, lilac tortie
boys - choc, lilac, red, cream

if mum is a black tabby then (and neither carry anything)

girls and boys - black (with or with out tabby)

if both carry dilute

girls and boys - black and blue (with or without tabby)

if mum also carries chocolate

girls and boys - black or chocolate (with or without tabby)

if mum carries carries chocolate and dilute and dad carries dilute

girls and boys - black, chocolate, blue or lilac (with or without tabby)

Does that help?

chocolate to chocolate tortie will give you only a limited number of possibilities:

chocolate and red males plus chocolate and chocolate tortie females (if neither, or only one parent carries dilute)

If both parents carry dilute then add lilac and cream males, plus lilac / lilac tortie females.


If mum is black tabby (non tortie) then you'd get

black, blue, chocolate, lilac males & females depending on whether parents carry dilute, and/or chocolate in the case of the black girl. Some or all would be tabby depending on whether mum was homozygous for the agouti gene.

wow thanks im going to sit and try and digest that all now!!! just to add to the mix, one kitten looks white? im guessing a point? recessive?

yes, couldn't be white so must be pointed

You're right, it's recessive so both parents must be carrying.

I thought you said you had done 5 years of research into cat breeding, why don't you know about cat color genetics?

Google "Cat color genetics" is a start.

brill thank you all so much for all your help im even more convinced mommy is a black tabby, and to be honest im questioning daddy's colour im so glad we can dna test colour, makes life so much easier hopefully i can convince the breeder to do it, so we know for sure what the babies are, saves the guessing game for the next generation!!

LOL - the Burmese Cat Club's mating chart was my bible when I first started breeding, but after all these years I now have it in my head - well the colours at least.
