This has been copied verbatim from another
web page I wrote and will be adapted to this site:DUNSKIN: cream, dun, and bay on black
Ongoing research: the amazing dun gene.
One can see the dun factor plainly on the first colt, Dusty, and his sire
was a cremello, so that makes little Dusty a dunskin.
That's black + bay + cream + dun genes.
--- The bay takes the black off the horse's body,
--- the cream lightens the resulting red to tan,
--- and the dun gene PUTS THE BLACK BACK ON IT! Undiluted.
It overrides the bay AND the one cream gene, in regard to black.

OSO DUSTY (name pending), a 2000 APHA gelding bred and
sold by by Gary and Bonnie Brewer,
Alchemy Acres, Wilton, California. Click on thumbnail to see full
size picture showing dilution of red bay color, shoulder barring, leg
barring and dorsal stripe. Also dun characteristics of neck marks,
outlined ears and eyes are present, but not the dark lower face
mask. Not every horse with the dun gene shows every
characteristic, but all must show at least a dorsal stripe and leg
barring to be considered a dun. Note that the black mane, tail and lower
legs of the bay base color is left intact. |

OSO DUN IT (name pending), a 2000 APHA gelding bred by Gary
and Bonnie Brewer, Alchemy Acres, Wilton, California. The
dorsal stripe is barely visible, but definite, and the lower legs are a
bit light due to this foal's young age, but they will darken in a few
months to black. OSO DUN IT is for sale and will be a regular registry
paint.

We are currently researching 2 apparent perlino duns, which are off-white
with "yellow" manes, tails and dun markings. If it turns
out they really are perlino duns, they show that the dun gene cannot stand up to
TWO cream genes any more than the black mane & tail can. They in effect
become, like the mane & tail, double diluted black.
In fact, that makes our suspected cremello dun having invisible dun markings (as
it would seem) just perfectly logical. More to come as this research unfolds.
