Color point chances in British Shorthair

Hi everybody,

My queen is now 7 weeks pregnant and doing fine. She mated with a lilac point BS whose parents were also color point BS. As for my cat she is a blue-cream tortie BS and her father was a lilac point coming from a point line whereas her mother was a cream BS ( coming from a cream line)
I would like to know what chances of geting point kittens do I have. I dont really know wheather the point gen and the color are related or if point is a non dominant gen ,.... any help would be appreciated

Many thanks !!!

If I have read this correctly, your queen comes from a lilac point sire and a cream mother. Your queen, therefore, carries the pointed gene.

Color and point restriction are inherited separately. The point restriction gene is a recessive. Consequently, either both cats must be pointed or must carry pointed. A cat inherits directly from each parent. Consequently, if your queen's father was a pointed cat, your queen carries the pointed gene.

You should also learn about the sex-linked red gene if you are planning on breeding tortie point Brits. Since your girl is a blue cream, coming from a lilac point male and cream female, she has inherited chocolate from her sire and she is a dilute. Bred to a lilac point male, you would expect to get blue, lavender, cream, blue point, lilac point and cream point males and blue, lavender, blue cream, lavender cream, blue point, lilac point, blue cream point and lilac cream point females.

Hi Barb and thanks a lot for your reply.
I hope we get some points from her though I love these cats so much that I dont really care what she has. Since you mentione the chocolate color. If I want to get chocolate ones what kind of Tom cat should I choose? Just curiosity. Or if you know a good site on cat genetics pls let me know I am very curious on this matter.
Oh well I am counting the days !!!

thanks

Hi there,

No problem. In order to get a chocolate from your queen, you would need to either breed her to a chocolate or chocolate point, OR black or seal point Brit carrying chocolate. I suspect that the CFA web site might have some info. on cat genetics - or at least color charts - at www.cfainc.org; but unfortunately I don't know of any sites you can visit. There was a very good book "The Book of the Cat" which has an excellent section on cat genetics, but I believe it has been out of print for 10+ years. If I'm reading properly that you are from the Nederlands, then am I correct in assuming that your girl is registered in Fife? If so, I should imagine that that association would have good information on genetics.

If the stud is a lilac point, then there was a chocolate behind him somewhere in his pedigree. Perhaps the stud's owner could put you on to someone with a chocolate Brit. Furthermore, if this is your first litter, then the stud's owner should be mentoring you and would probably be happy to explain genetics to you.

BTW, it's probably inconceivable that you won't get at least one pointed kitten in your litter. Good luck with the babies!
