Cat Genetics Tutorial Part 4 (White)

Description

This tutorial is out of date. Please see more information here.

    There are multiple cat genetics tutorials about, but they tend to only cover the basics (base colors, dilutions, tabby, white-spotting, pointism, & tortie/orange). In-depth cat genetics tutorials tend to be lacking. So thus, this. I have no idea how long this will take to be completed. Hopefully before 2016. 

NOTE: THERE IS A MISTAKE!
There should be no wild type at all on this part. I accidentally added wild type to Grade one and roan/tweed. This will be fixed as soon as possible

    Part four is finally here. White-spotting and other white markings are up next. White-spotting is a very common trait, so a randomly chosen moggy probably has white-spotting. White-spotting is split up into ten grades with increasing amounts of white. Dominant white is a dominant gene, but happens to be rather rare. A dominant white cat is born with a patch of color on top of it's head, and this patch usually fades away before the cat is a year old. Next up are weird and unusual mutations. Quite honestly, no one knows what causes any of these mutations. Sheeted cats occasionally have a much thinner stripe which is called belted. Normally the European mutation has less white speckling, with the white speckling more towards the white points. Sometimes there are no white speckles at all, just the white points. Roan/tweed is unusual, and just adds white hairs intermingled with colored hairs. The amount of white hairs to colored hairs varies, but it tends to lean toward more colored hairs. The Finnish mutation is a mutation that comes from an inbred colony of cats in Finland. This mutation is associated with infertility, and it is unknown whether the mutation causes the pure white markings, or if that comes from white-spotting. The Moscow mutation is a snow leopard-esque mutation originating in Russia. Notice the silver hint to the coat except for the white muzzle. Since white-spotting normally comes from the bottom to the top of a cat, skunk stripes are unusual. Notice the 'frame' of white. Brindled is pretty much a tortie with white instead of red or cream. This could be a somatic mutation or a genetic mutation. Swirled markings are asymmetrical, and it could be a mutation or an unusual expression of white-spotting. The skunk stripe could be that too. And onto the last one: unusual spots. These are strange spots of color in white-spotting. Colored muzzle/chin spots are rather common, but speckles on paws, patches on toes, and reverse lockets not so much. Nose colors tend to turn pink or have pink patches.

    Here are some good white-spotting terms worth noting:
Locket - Small patch of white on chest (Grade 2)
Button - Small spots of white on belly (Grade 2)
Tuxedo - Black with white paws, belly, chest, and muzzle, white tail tip possible (Grades 3-4)
Mask & Mantle - White with colored head, and back & tail (Grade 6)
Harlequin - White with random white patches (Grades 7-8)
Piebald - 50% white or more (Grades 5-9)
Mitted - White paws, other white markings possible (Grades 2-4)
Van pattern - White with colored tail and head spots (Grades 8-9)
Moorish-Headed - White with colored tail and head (very rare, Grade 9)
