Sand, A/* sd/sd
At least one copy of Agouti, and two copies of the Midnight Blue gene.
Variety not recognized / standardized in any clubs
Chromosome: Unknown
RVG description:
A gene that is not very common in the fancy but has been documented by Alan Gangi on non-agouti varieties.
Alan talks about this gene to be called Sand in older papers and has been designated the genotype sd. The sd gene only affects black/brown pigment so it will not affect yellow/red pigment. This means that varieties such as Beige, Fawn, Silverfawn and other yellow toned varieties will not be affected by the sd gene.
