The "New" Dilutions

Pearl --- Light Black ---
Unknown

Other Dun --- Mushroom --- Hanoverian Cream
The NewDilutions list (see bottom of this page) and
web site
were founded to study and document color dilutions
that
could not (YET) be explained by known equine color genetics.
It immediately
took on another function : that of explaining and
tracking (initially) the
previously "unknown new dilutions"
which are now known to be
one, and caused
by one gene,
which we named Pearl.
Click on a photo, above, to see the page about
that particular horse, or a link, below, to see the section about
each color phenomenon.
This webmaster has been contacted through the
years by folks wanting to know about the "mushroom" color in ponies.
For many years, it was on our "back burner", especially
since it seemed, at first, to be simply explained by "silver".
Now it's known that red (ee) ponies show this dilution (which therefore
can't be "just silver"), plus there has been a new form of
red (e) discovered that is quite possibly the cause. At
this time, it seems to exist only in a very few English Shetland
Pony families.
The newest dilution gene discovered, "Pearl",
not only occurs in Andalusians, Lusitanos, Pasos, and American Paint horses, but has also been confirmed to exist in
the breed(s) known as Gypsy Horses. (See the Pearl section,
and then follow the links to the Gypsy Horse examples.)
Congratulations and kudos to the
members of newdilutions@yahoogroups.com, Carolyn Shepard, Dr. Cecilia Penedo at UCDavis,
and all of you other equine color researchers
and horse owner/breeders
who worked to identify, name & rename this rare and amazing, elusive, recessive
and cream-activated gene.
DNA Color Testing
If you wish to have complete documentation of your horse's
color (breeding) potential, you should have your horse DNA tested for as many
color genes as he/she could possibly have.
This group gains no profit from
any of these labs; the above is simply our opinion. If you wish to look
into testing your horse, you may consult the list of all labs of which we know and
the tests they are currently able to here, HERE.
If you know of changes that should be made to that
page, please contact the web master. |
