oh, yeah, thanks zenzan.
how do i do the test, exactly? i think i can do this now :3
So you know everything?
black factor, red factor, tabbies, silvering, C locus, white spotting, deformities, and hybrids?

Practicing:
All correct! Nice work. :3
pretty much.
Awesome thanks, Zen! C:
... //facepalm
I need to finish my red factor... o.o I should probably do that.
pretty much.
mini test, then? :3
footy;; did you want some more practice questions?
For reds? Sure. I still don't fully understand the second section of the lesson.. o.o
which part isn't sticking? Maybe I can rephrase it for you. :3
red tabby x chocolate
cinnamon tabby x cream tabby
lilac x dilute torbie
QuoteDisplay MoreAnother important note. When the male kits inherit a black factor X-chromosome, they can still take on colors from their father. I'll use the following pairing to better explain;
Chocolate tabby x Cinnamon tortoiseshell.
In this situation, say a male kit inherits the mother's black X-chromosome, which contains cinnamon. Putting the red factor completely aside now, you have a "chocolate tabby x cinnamon" scenario; thus, thanks to the chocolate father, the male kit can also be chocolate (and WILL only be chocolate unless the chocolate parent is carrying cinnamon).
Red factors can also "mask" other colors, similar to the way that white does. I'll use some more pairings to elaborate...
Black (carrying cinnamon) x Cream tabby.
From this pairing, let's say we get a male kit. Because his mother is a cream tabby, he can only inherit her red factor X-chromosome, and he ends up being a red tabby. Meanwhile, he inherits the genes for a solid black cat from his father -- you just can't see it because the red is masking it.
This red tabby male grows up, and has kittens with a cinnamon tabby.
Red tabby x Cinnamon tabby.
Males: Brown tabby, Black, Blue tabby, Blue, Cinnamon tabby, Cinnamon, Fawn tabby, Fawn.
Females: Tortoiseshell, Dilute tortoiseshell, Torbie, Dilute torbie, Cinnamon tortoiseshell, Fawn tortoiseshell, Cinnamon torbie, Fawn torbie.
You'll notice that the males can be blacks -- but how is that possible if the mother is cinnamon? The males can't inherit their father's red X-chromosome (because, as males, they'll always take his Y-chromosome), which means that their genetics are to be worked out with black factors only. And because the red tabby parent is masking solid black w/ recessive cinnamon (from his own father), the genetics for the red tabby's sons can be found by substituting the original pairing with "Black (carrying cinnamon) x Cinnamon tabby".
If you know that, the genetics for the male kits are a lot easier to work out.
When doing WCRPG genetics, like with white cats, you'll find that people won't often specify what the red factors are masking, and you won't usually know who a random red (or cream) tabby's parents are. It was suggested to me by a geneticist that the default color masked by red factors be solid black (carrying whatever recessive genes the other parent might have) for maximum variety; however, what you make it mask is up to you.
* NOTE: Red masking applies to female cats the same way it applies to males! I know that I only pointed out red masking with the males in the above examples, but don't forget that the rule applies to both genders. *
^That.
And just give me a moment to do the practices.

cinnamon tabby x cream tabby
Males: red tabby, cream tabby

um.
oh boy. That's long and skirts around a little. XD
so most of that can be explained if you take a good long look at this post I did a few pages back:
http://warriorcatsrpg.com/inde…4.msg67303582#msg67303582
But Chrono used X and x's, and I used O and o's. Just keep in mind: capital = red factor, lower case = black factor.
Now the gist of what most of that quote is saying is that assume red tabby/cream tabby to mask black:
OY BB Dd aa = red tabby
OY BB dd aa = cream tabby.
And like black and blue and any other dominant color, when there's a recessive colored partner, you have them carry their color as well:
red tabby x chocolate
OY Bb Dd aa x oo bb Dd aa
Needless to say, any red tabby/cream tabby litters will have black and/or blue and their variants in the answers.
As for torties...
think of them like black factor. Except for a few minor changes:
black = tortie -> Oo BB Dd aa
blue = dilute tortie -> Oo BB dd aa
brown tabby = torbie -> Oo BB Dd Aa
blue tabby = dilute torbie. -> Oo BB dd Aa
The other two black factor colors (and their dilutes) are just written with "tortie" at the end, or "torbie" if they're tabbies.
examples:
chocolate torbie = Oo bb Dd Aa
cinnamon tortie = Oo b1b1 Dd aa
lilac tortie = Oo bb dd aa
fawn torbie = Oo b1b1 dd Aa
Things like that.
Does that make more sense?

I'm not really doing that. I'm doing the actual genetics. Also a Blue tabby x chocolate solid will never be a solid. It will always be **'**'Aa'**, because of the blue's tabby marks. I expand the color options one when doing WCRPG litters, because people make characters that aren't always realistic ie brown, chocolate underside, and white fawn mark. Fawn mark doesn't apply to cats naturally, and I don't think anyone would dye it like that...

All she's saying js that that is how genetics are done on the site. She's trying to help. And a blue tabby paired with a chocolate woukd result in solids and tabbies as well, of each colour seeing as its dense and a dilute.

Blue tabby x chocolate solid could lead to a solid if the tabby was already Aa. Aa x aa = chance of both Aa and aa kits. And it could lead to dilute kits if the chocolate cat carried dilute (genotype Dd); and it could lead to chocolate-based kits if the blue tabby carried chocolate (genotype Bb).
And on this site, we assume all tabbies, except wildcats, are Aa; that all nondilute cats, except wildcats, are Dd; and that a cat carries any recessive allele expressed by its partner (for instance, in a chocolate solid x seal point litter, we assume that the chocolate cat carries point - genotype Ccs on the point gene - and that the seal point carries chocolate - genotype Bb on the black factor gene).
Is that the way it is in real life? Not all the time, no. For the rarer recessive alleles, it is pretty unlikely in real life that a random cat will happen to carry the allele. (Although it does happen, and the main characteristics of some breeds have been discovered by a recessive allele unexpectedly being showing up in kittens - for instance, the lykoi mutation, or some of the rexes.)
But: does it make the RPers happy when instead of being told "all your kits will be brown tabbies, there is no other choice" they get "your kits can be brown tabby, blue tabby, chocolate tabby, lilac tabby, black, blue, chocolate, or lilac"? Yes, it does - because they can get a family resemblance thing going if they want a kit to resemble the blue tabby or the chocolate parent; or they can simply have a greater variety of pelts and not have all their characters look the same.
And the more people are satisfied with our work on the genetics board, the more people will actually use our services, instead of just making their litters free-for-all (and thus, totally genetically unrealistic) because the genetics they receive are too boring.
We strive to strike a balance between realism and popular appeal here. Yes, realistic genetics are important, but if nobody was willing to use the genetics board, then its existence would be pointless.
(If I've worded anything offensively or incorrectly here please let me know. I seek to explain, not to insult or offend, but I'm not real good with people and I often don't know how my words are going to come across.)
