We are taking a summer break from December 21 to January. You can still place orders now and while we are on break. If we we receive but don't finish testing your samples before Christmas they will be at the top of our list when we re-open in January. Samples that arrive during the break will be stored carefully for testing in January.
Thanks for all the testing you've sent us this year, and have a wonderful summer!
W22 dominant white (W22)
Summary
W22 is a version of the KIT gene that produces a partial to completely white coat pattern. W22 is thought to have originated in an USA-bred Thoroughbred mare called Not Quite White, born in 1989.
Not Quite White had at least two white foals. The most well-known is Airdrie Apache (a stallion). She also produced a filly called Spotted Lady. Most W22 horses are descended from Airdrie Apache.
No horses have been identified yet carrying two copies of W22.
