The basic principals of CAT genetics:

-> The male kittens in a litter, inherit their colourings from their mother.

-> The female kittens in litter, inherit their colourings from a combination of their mother and father's Colour.

-> You can only breed a genetic red or cream female, if the father is a genetic red or cream, and the mother contains red or cream factor.

-> The colours and patterns in a pedigree, do not directly affect the Colour of the kitten - it is only the parents that can influence this, except where the recessive gene is      inherited eg, blue,      chocolate, lilac, colourpoint.

-> A dominant characteristic cannot skip a generation. If the characteristic is there, it will appear in each generation.

-> Cats of a dominant Colour, will have a parent that is dominant also.

-> A dominant cat can only be produce if either or both parents are dominant.

-> Two recessive Colour parents (Blue, Cream, lilac etc.), cannot produce a cat of dominant Colour (Red, Black, Tortie).

-> Two Colourpoint (siam point, burmese point) parents will only have Colourpoint kittens.

-> Colourpoint kittens must have parents that are, or carry Colourpoint.

-> No Colourpoint kittens will be born to parents if one does not carry Colourpoint.

-> A tabby (agouti) kitten must have at least one parent that is a tabby or shaded.

-> A shaded cat must have at least one parent that is shaded.

-> Shaded parent can have smoke kittens, but smoke parents cannot have shaded kittens.

-> Bi-Colour kittens must have a least one Bi-Colour parent.

-> Spotted (agouti) tabby kittens must have at least one parent that is a spotted tabby.

-> Mackerel (agouti) tabby kittens must have at least one parent that is a mackerel tabby.

-> Solid cats as black, blue, red, cream, chocolate and lilac (without agouti) cannot have agouti kittens
