Emmm....can I try........

Blue tabby carries black gene, dilute gene (dd) , tabby gene
Black tabby carries black gene, tabby gene maybe some dilute (Dd)
Red van carries red gene (Xo), white spot gene(SS), tabby gene, probably some dilute gene.

Offspring probably will be like following
Female : Calico, Dilute calico
Male : Black tabby & white, Blue tabby & white

All kitten will be with white because of the white spot gene (SS)
Didn't know whether the cat carry any chocolate gene or not.
If there are some chocolate gene, then you add in chocolate/lilac in the offspring list.

All above is just my prediction base on the fenotip, if there something that I miss out, feel free to correct it.

Blue tabby (female) x Red Van (male) -Very little red, only a few spots
you will end up with blue tortie,tortie, tortie van,you might even have red,not sure about white.or also bi-color red or bicolor blue tortie. the odds of having van patern is 15 persent and bi-color are 30 persent.the odds of getting solid red and calico might be high.and also any of those color but with tABBY

Black tabby (female) x Red van (male)
you will end up with toirtie tabby, tortie solid,brown, and even blue.you can also end up getting solid red and solid black of another black tabby.
but what i know yes red is a recessive gene but then gene cannot be decrese or make it go away .the gene is still there whether you like or not just when it comes out it end up getting very little red or any other quantity of color even though your red vaN HAVE VERY LITTLE SPOT OF RED THE GENE OF RED IS STILL THERE. thats why the odd or getting tortie is high to any colored cat as long as the cat have a red gene and the other one got a dark color you will end up getting tortie.
yeah well thats what i know so at least that s why i think.but i know that gene cannot be decrese or make it go away.

At first, that's what I thought! Now that you put it that way, I think it's possible. It would be much easier to guess the probability if we know the color of the parents.

Hmmm.... this is interesting... huhu... calico the bomb! Hehe... thanks Shadow!



Yup, red is recessive. I like the fact the offspring could have the chances of being a tortie. Also some bi-color. Meaning it could be able to have all colors , red, black, white. (either with dilute/tabby/solid/bi) Hmm.... this is really interesting! What a thrill being a breeder. I guess with Pedigree cat it's easier since the parentage is recorded. Thanks for your input maxackles!

Anymore suggestions and ideas, opinions on this matter y'all! Lesley maybe?

I get what you're saying (that red can be SOO hard to see in some cats...just a few hairs between the toes) but that's not (strictly speaking!) recessive. Red is dominant, so if a cat throws red, it must BE red itself. Either obviously so or 'hidden'!

The absolutely best reference I know of is the FIFe
'Colours and Patterns' book, available through the FIFe online shop. A wonderful reference which covers all possibilities of 'normal' colours. (Like a blue carrying choc and dilute mated to a red female carrying cinnamon and dilute will give you.....) If you're half-way serious, buy one!

That's a thought. It could always be a start.
This is interesting, I guess one doesn't have to be a breeder to know these things... thanks for the suggestion!

Very interesting indeed!

All the kittens born from solid and van mating will be bicolour or calico. You won’t get van or solid kittens.

Mating between Black Tabby (female) x Red Van (Male) and Blue Tabby (female) x Red Van (male) will produce Calico, Tabby-Calico females and Black Bicolour, Brown Tabby Bicolour males. The second mating between Blue Tabby and Red Van, if the male carry dilute gene then you get additional colours: Dilute Calico and Dilute Tabby-Calico females and Blue Bicolour and Blue Tabby Bicolour males. Assuming both parents don’t carry chocolate or lilac gene. If only one parent carry chocolate or lilac gene, won’t be enough to give you chocolate or lilac kittens, as both genes are recessive genes.

Lesley is right about red being dominant. You don’t get red in the above mating because males only carry one colour whereas females carry 2 colours. In these cases, the male red colour is only passes to the daughters and not the sons. The daughters also receive one black or blue colour from the mother to produce Tortie or Blue Cream and with additional white colour, they become calico or dilute calico.

Ahhh Pussy! Thanks so much! This really helps! Will do more reading on this topic. Now I know what color I want for my male... if I ever need one!
