    jus though we cud start a new thread on this. I think iv gt my head round this a lil now, so if we have a blue-tabby cp queen mating with a cream cp stud does this mean you will get females;blue/cream. males;cream or blue and tabbies and are all those cp's

    For anyone just starting out with British and trying to get their head around genetics - colour genetics particularly - I'd highly recommend you have a read of the new British Shorthair Breeding Policy. 'Dozymoo' kindly put a link on here (somewhere!) to it... I'll try to find the thread for you, but a general search on the 'net will find it. It is still in draft form, it is very long and, genetics seeming a bit of a tough subject, it might look confusing at first. But it's beautifully written and contains a wealth of information.

    The good thing, of course, is that it's breed specific and I personally think it's a bit of a bible for anyone who breeds/shows BSH. I wish it had existed when I started breeding; I spent years with one book which ended up in tatters from overuse, trying to get my head round it :)

    GSkinner123 is right, the new British Shorthair Breeding Policy is really helpful. It is still being updated but the information is very indepth, and although it is specific to Brit's, the basics could be applied for other breeds. I've found it a very interesting and thorough piece of writing.

    Just click on the Breeding Policy tab at the below site and download the PDF!

    Home - British Shorthair BAC

    It is also a great source of information for best practices, detailing which matings are and are not recommended in British Shorthairs.

    :)

    I dare you to take another read of the breeding policy and come back and tell us the answer :D

    The choc CP male cannot carry some of the colours you mention, even though they are in his pedigree as some colours simply cannot be "carried" by another. He can carry the dilute of chocolate, which is lilac. It matters not that he has non-cp ancestors as he, himself, is a CP. The CP gene is recessive to (i.e. may be carried by) self - so you can have a non-cp cat carrying CP but not a CP carrying self. (Boy, I'm rubbish at explaining things).

    Colours of kittens from the mating you've mentioned would depend entirely upon whether the female carries CP; whether the male carries dilute; whether the male is masking classic or spotted (or even ticked) tabby. It will also depend if the female is homozygous or heterozygous for 'tabby'. That simply means if she has two copies of the 'tabby' gene she will only ever produce tabby cats; if she has one copy for self, then she can produce both tabby and non-tabby kittens. Totally depending on all/any combination of those factors female kittens would be chocolate, chocolate tortie, lilac and lilac tortie, whether self, cp, or tabby of some form. Males - chocolate, lilac, red and cream, again whether self, cp, tabby.

    I've managed to confuse even myself with all that :)
