Artistry was sired by a proven perlino
dun stallion, so a dun gene along with the pre-requisite
cream gene, was certainly a possibility.
When Artistry was born, his dorsal
was especially intriguing, as it was shaped exactly
as a dun dorsal would be, and it was very clean
edged. However, Artistry's tail showed almost no
dilute frosting, which is not typical of a dun dilute
foal. Dun dilute foals generally have an abundance
of tail frosting. Even bay foals can often have
quite a bit of lighter foal tail hair. But, brown
and brown buckskin foals, on the other hand, generally
exhibit little to no foal frosting in their tails
Primitive leg barring was also present
on Artistry's front legs. But the extreme lack of
tail frosting was reason enough to have serious
doubts that he inherited his sire's dun gene.
Thankfully, the dun zygosity test
was available via UC Davis, and his breeder was
able to have his color verified scientifically.
Artistry's dun zygosity test results showed no dun
dilution was present. Artistry was confirmed to
be a buckskin, not a dunskin.
Once he shed his foal coat, his
color became even more clear. His overall darker
body coloring is indicative of brown buckskin, further
confirming that he does not have a dun gene, as
his color expression is typical for brown buckskin,
but not for any of the dun dilute colors.
