Mutation monday- a day late again, sorry
Share a picture of your mosaic!
Wilson White was discovered in 1955 in California by Mrs Blythe Wilson. Wilson whites are an incomplete dominant. This means that they only need one parent of this color to produce it. Being ‘incomplete’ means that it allows other mutations to show or have spots of color. A Wilson white is a standard plus a white gene (so white with potential standard spots). Mosaics can range greatly from pure white to silver to darkly spotted. A mosaic will always have dark eyes.
Wilson whites are also called mosaic, silver, white, extreme mosaics, and other terms; but the most common are mosaic in the USA and Wilson white typically overseas. For showing whites are divided into predominantly white (all white with dark ears/small spot on the base of the tail only), white with dark guard hairs, mosaic (any white with a spot of color), pink white/white with pink ears (pink whites, tan whites ext-these mutes will have their own week for pictures), and silver (even gray tone over the whole animal). While these are all the same genetically, they are all different looks.
Breeding whites can be quite challenging since spots and other coat patterns cannot be aimed for and rarely breed true. It’s completely a roll of the dice. On very special lines you may find that some throw darker markings or not markings at all.
When breeding, a white should never be paired with another white. This is called the lethal factor. Genetically the embryo does not develop and is reabsorbed by the female. While no specific studies have shown negative results, long time breeders have seen higher cases of infertility and unexplained death of the female in these pairings. Pairing a white to a white also results in lower quality offspring, which is not the goal of a responsible breeder and is avoided.
Whites/mosaics have a natural tendency to be ‘yellow’ (off colored) and ‘cottony’ (a soft coat that does not stand up correctly). A white that is not bright white or one with weaker fur is sold as a pet.
