*Please do not choose a feather sample for Silkies who do not yet have real feathers. This does not work with chick down. Please use blood spots on a plain piece of white paper or an index card for birds that are not old enough to have real feathers yet.
About Dominant White
Dominant White is a mutation in the PMEL17 gene. It interrupts the way black pigment is laid down in the feather, so a bird that is genetically black comes out white, often with a few black spots or flecks as a chick. Because it is dominant, a single copy will show, and it can be passed on by a bird you would never guess was carrying it.
This test tells you whether the bird carries the Dominant White mutation, which is the piece most breeders need before pairing a white bird into a colored pen.
Smoky and Dun are separate mutations of the same gene and are sold as their own tests.
