    All female mammals (including humans) have two X-chromosomes and males have a Y-chromosome (which is the reason they are male) and one x-chromosome.


    The red gene is located on the x-chromosome. XO = Red X-chromosome and Xo = Non-red X-chromosome. So in order for a male cat to be red they only need one red x-chromosome (this is because the Y-chromosome is too small to hold any color genes on it). So a red male would be XOY and a black(chocolate, cinnamon, blue, lilac, or fawn) male would be XoY.


    A red female needs to be XOXO. A black(chocolate, cinnamon, blue, lilac or fawn) female needs to be XoXo. Now if a female has one red x-chromosome and one non-red x-chromosome they would look like XOXo. This means that the black color can show through in some spots and will be red in other spots. The black color you see in a tortie is the masked color underneath.


    Yes that is correct :D


    Wow....my brain must have died....I was looking at the females and got so excited that those were correct that I completely ignored the males. Thanks to the post below I was quickly reminded that all males would be red or cream tabbies. *hits head against laptop* I should have caught that. :o

    Red Tabby w/White (Van) x Black w/White


    Females: Red Tabby w/White, Cream Tabby w/White
    Males: Black w/White, Blue w/White


    All kittens born will have white. Half of the kittens will have the van pattern (only the head, tail, and sometimes a spot on the back will have color and the rest of the cat will be white) and half of the kittens will just have some white.


    Eyes: Any realistic eye color including blue.


    Van Pattern:



    Red Tabby x Blue and White


    Females: Tortie, Dilute Tortie, Calico, Dilute Calico
    Males: Red Tabby, Red Tabby and White, Cream Tabby, Cream Tabby and White


    Eyes: Cats with white (including calicos) can have any realistic eye color including blue. Cats without white can have any realistic eye color except blue.


    Chocolate and White x Silver Tabby and White


    Black, Brown Tabby, Silver Tabby, Smoke, Blue, Blue Smoke, Blue Tabby, Blue Silver Tabby, Chocolate, Chocolate Smoke, Chocolate Silver Tabby, Chocolate Tabby, Lilac, Lilac Smoke, Lilac Silver Tabby, Lilac Tabby


    Any kits can have white.
    Eyes: If they have white they can have any realistic eye color including blue. If they do not have white they can have any realistic eye color except blue. Let me know if you need any color reference photos :)


    You forgot that with a torbie female (XOXo) and a non-red male (XoY) you can also create non-tortie females.


    Correct. You can also mention that a tortie w/white is also called a calico (just in case they don't know).



    You forgot the blue tortie female. Also there cannot be any cream tabby males. Also you forgot the blue male. Think of the cream tabby as a cream solid so there wouldn't be any tabby options.



    You forgot the cinnamon, cinnamon tabby, fawn, and fawn tabby options for males. And cinnamon and fawn torties as well as that females can also be non-torties. So they can also be Black, Blue, Cinnamon, and fawn solids and tabbies.



    The female can only pass on her red x-chromosome so there will only be red and cream tabby males.



    You forgot the females :P Also you forgot the black and blue for males. Also remember that you want to think of red tabby as a red solid. So there wouldn't be any tabby options.



    You forgot the female options since they can also be non-torties. They can be black, blue, brown tabby, and blue tabby.



    Both cats are dilute so there wouldn't be any non-dilute options. Also females can be blue and blue tabbies as well.



    You forgot the female options. They can also be white, black, blue, brown tabbies, or blue tabbies.



    You forgot the females lol. Also there would also be blue tabbies for the males.



    NINJA'D lol


    ^ MistyBlue2010: I've been told to assume red tabbies cover brown tabby, this is probably where the tabbies showing up in red x non-red-solid litters come from.


    Oh okay because I keep hearing different things from different people. I wish frostsoul would make a sticky of all of these rules so people stop changing them.

    Also I should mention that when you have a non red male bred with a tortie/torbie/calico/torbico cat, that you will be able to get female cats who are black, chocolate, cinnamon..etc. It is only when the male is red that you can never get those colors in females.


    Don't forget about cinnamon. It is also a black factor color :)


    [align=center][color=white][font=helvetica]on the first, I don't think that the males can be any blacks c: only chocolate.


    on the second, the males can also be black//blue, the females can be dilute torties, and both red and cream tabby for the fems are correct :3


    I see so many mistakes in my genetics test <//3 guys I'm scared for Frosty's response


    Remember that red tabbies mask black so there can be black options for the first.

    Here is a simple equation to think about for reds...


    *Black Base refers to either black, chocolate, or cinnamon*



    Red Tabby [Masking Black Solid] x [Black Base] Solid


    Females: Tortie, Dilute Tortie, [Black Base] Tortie, [Black Base Dilute] Tortie
    Males: Black, Blue, [Black Base], [Black Base Dilute]



    Red Tabby [Masking Black Solid] x [Black Base] Tabby


    Females: Tortie, Dilute Tortie, Torbie, Dilute Torbie, [Black Base] Tortie, [Black Base Dilute] Tortie, [Black Base] Torbie, [Black Base Dilute] Torbie
    Males: Black, Blue, Brown Tabby, Blue Tabby, [Black Base], [Black Base Dilute], [Black Base] Tabby, [Black Base Dilute] Tabby



    [Black Base] Solid x Red Tabby [Masking Black Solid]


    Females: Tortie, Dilute Tortie, [Black Base] Tortie, [Black Base Dilute] Tortie
    Males: Red Tabby, Cream Tabby



    [Black Base] Tabby x Red Tabby [Masking Black Solid]


    Females: Tortie, Dilute Tortie, Torbie, Dilute Torbie, [Black Base] Tortie, [Black Base Dilute] Tortie, [Black Base] Torbie, [Black Base Dilute] Torbie
    Males: Red Tabby, Cream Tabby



    *Remember if both parents are dilute, there will only be dilute kittens*
    *If one parent is dilute and one parent is non-dilute, there will be both dilute and non-dilute kittens*
    *If two parents are non-dilute, there will be both dilute and non-dilute kittens*



    ~Edit: Forgot to add the torties~



    Red Tabby [Masking Black Solid] x [Black Base] Tortie


    Females: Tortie, Dilute Tortie, Red Tabby, Cream Tabby
    Males: [Black Base], [Dilute Black Base], Red Tabby, Cream Tabby



    Red Tabby [Masking Black Solid] x [Black Base] Torbie


    Females: Tortie, Dilute Tortie, Torbie, Dilute Torbie, Red Tabby, Cream Tabby
    Males: [Black Base], [Dilute Black Base], Red Tabby, Cream Tabby



    [Black Base] Solid x [Black Base] Tortie


    Females: [Black Base] Tortie, [Dilute Black Base] Tortie, [Black Base], [Dilute Black Base]
    Males: Res Tabby, Cream Tabby, [Black Base], [Dilute Black Base]
    *If both black bases are different than add those colors into the formula as well*


    [Black Base] Tabby x [Black Base] Torbie


    Females: [Black Base] Tortie, [Black Base] Torbie, [Dilute Black Base] Tortie, [Dilute Black Base] Torbie, [Black Base], [Black Base] Tabby, [Dilute Black Base], [Dilute Black Base] Tabby
