oh this all seems so confusing!! i understand dominant and recessive but not the bases or dilutes!!

I have a chocolate female, her mother was chocolate and her father was lilac. From what I have read as for lilac to be shown it has to be a double recessive which would mean my girl carries lilac, is this right?

Also how does it work with colourpoints and selfs, which is dominant?

Yes your girl would carry dilute (or lilac) from her sire. You do need 2 recessive genes for that recessive to be expressed.

Colour points are caused by a double dose of the cs solourpoint gene which is recessive to the dominant C self gene. So if you mate 2 colour points together you will only get colourpoints. A self carrying colour point to a colour point, 50/50. Two selfs carrying colour point 75/25 (self/colourpoint)

The base colour only comes into play if you have a red/cream or apricot cat.

oh ok then, thats starting to make sense thank you. so if i put her to a lilac colourpoint i would get mostly lilac selfs as the lilac colourpoint must be double recessive to express the lilac, and the self would be dominant over the colourpoint?

Unless she carries colourpoint, then you would get all selfs with a 50% chance of the kitten being lilac. If your girl carries colour point, then you would have a 25% chance of a lilac colour point (if I remembered how to work out probability correctly :confused: )

% probabilities are only a guide though, Mother Nature does what she likes :cool:

thank you very much. now a year old so need to find a stud cat and wait for her to come into call! would like some lilac kittens as think they're beautiful!

I have heard that as chocolate is a dilute of black (not sure about this bit) that if I were to put her to a blue then i would most likely get black kittens?

Its easier to think as chocolate being a different colour to black, rather than a dilute. Technically I think there is only one colour and that is black, but in a chocolate cat something happens to the colour distribution within the hair and it comes out chocolate, but thats way too confusing.

Chocolate is a non dilute colour in its own right but recessive to black. So a black (or its dilute blue) cat can carry chocolate, but a chocolate could not carry Black. If you mated your choccie girl to a blue (blue is the dilute of black, so like the lilac carries 2 dilute genes), who didn't carry chocolate you would have a mixture of black and blue kittens - all of whom would carry chocolate. If the blue also carries chocolate you can add chocolate and lilac into the mix.

i love genetics, always was interested at school and bred horses so fascinating, this is my first foray into cat breeding so lots to learn. good to know chocolate is its own colour, didn't really want to end up with black from everything as its such a dominant colour!! fingers crossed for the lilacs then.

Hi new to this please can you tell me if I mate a red tabby female to a blue stud what colour litter should I expectrl?

Hi Sharon
I think you need to start a new thread. This one is several years old and neither saikou or Liz post here anymore. We do have other members with a good knowledge of colour genetics though

HI please could you tell me if I mate a red tabby queen to a blue stud what colour litter to expect? Mum of Queen was cream and dad red. Mum of blue stud was blue dad cream.

It's a lengthy permutation of possible colours/patterns to predict without knowing a number of factors -

- when you say tabby queen, do you mean classic, spotted or ticked tabby?

- has she been DNA tested to show that she IS an agouti cat? More than half of red based "tabby" BSH are shown to be self (non tabby) on DNA testing. So if she is indeed self and not tabby, none of her kittens can be tabby

- does either, or more to the point both, parent carry chocolate? If only one or neither parent carry chocolate, chocolate/lilac series kittens are not possible.

- what pattern is the blue stud masking? A self will mask one of three patterns - ticked, spotted or classic. Depending upon your girl's pattern, the pattern the stud masks will have an effect. For example, if your girl is classic tabby (bottom of the 'ladder' in terms of recessives) and the stud not masking classic, then classic tabby kittens are not possible.

Clearly she carries dilute so to a dilute stud, dilute kittens are possible and basically speaking they - and all kittens whether self or agouti - will be red series males and tortie females.
