So... Recently I've had a sudden interest in cat genetics... And I will explain... As best as I can. X chromosome: This is the only one that effects the biological gender of a cat. Males have XY and females have XX. The base color of a cat resides in the X, so males can only have one base color unless there's chimerism, where two embryos fuse together with different base colors, or klinefelter, where they have XXY or XXXY. Why us this, though? We'll, males have to get a Y from their father, which doesn't have a base color in it. Females, on the other hand, they are mostly torties or calioes because they get an X from both parents, and they can only be one color if they get a X from each parent that has the same base color. Now, there's more. The base colors are only orange and black, but the loci make different colors. An orange X would have a subscript o, but apperebtally my keyboard won't let me do that cause it has to be at the bottom >:( B locus: This is what creates brown. Now, if a cat has orange X(two of them for females) that covers up all of the b locus. Now, B, pronounced big b, is black. It's the most dominate, so if you have Bb, only black will show b, pronounced little b, is a basic brown. b', pronounced b prime, is chocolate or light brown. The only case in which b' will show, is if they have b'b', because it is the least dominate. Next, The s locus: The s stands for spotting, and it controls the white spots Now, a bit of a clarification. Technically, S = lots of white, but the person I learned it from, messed up, and they did it flipped. So, I will tell you what the real thing is, but if I do more projects on cat genetics I will do it how I learned So, SS: lots of white Ss: some white ss: no white. It's pretty simple here Locus d: This controls the dilution, or brightness. D: not dilute d: dilute This is where gray comes in. So, if you have a basic black X, if you dilute it, it turns to gray. Then the locus b also changes and just makes it a different shade again. A/agouti locus A: multiple colors, so it mostly occurs in female cats, can can only show in female cats a: solid color T/tabby locus: This is the only pattern locus I know, so I'll have to do way more research Anyways, So, the first one is tickled tabby, which is like... you sprinkled salt on a cat...? It's sorta hard to explain, but it has the locus Tiª. Now, for the actual tabby patterns and stripes to show through, you need to have Ti+Ti+, which gets rid of the tickled pattern. Now, mackerel and blotched are the two others I know :) So, Blotched: Tb Mackerel: T Yeah... They are supposed to be the tiny letters at the top, but my keyboard won't cooporate... anyways, I(i) locus: This makes the fur completely white except the tip, making it look shiny I: shiny i: not shiny L locus: This is fur length L: short fur l: long fur That’s all, and I might do something where I make Warrior Cats genetically accurate, but that will take way more time than this project, so it won’t come out for a while.
