The "Newest" Dilutions

NewDilutions exists to investigate color dilutions that cannot (YET) be explained by conventional equine color genetics. It recently took on another function : that of explaining and tracking (somewhat) the previously "unknown new dilutions" which are now known as Pearl.

Now:  "Mushroom"

This webmaster has been contacted through the years by folks wanting to know about the "mushroom" color in ponies. 
For all of those years, it was on our "back burner".

Time to put the pot on "full boil"!  Let's find out why red (ee) ponies show this dilution (which therefore can't be "just silver"), and if it's a known gene that just looks different in these ponies, or a completely different gene that exists only in those few herds.

THE LATEST NEWS: PEARL in GYPSY HORSES

The newest dilution gene discovered, "Pearl", not only occurs in horses descended from My Tontime (granddam of Barlink Macho Man), Andalusians, Lusitanos, and Pasos, but has also been confirmed to exist in the breed(s) known as Gypsy Horses.

Older news: 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 amazing, elusive, recessive and cream-activated gene.

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 has no interest in any of these labs; the above is simply our opinion.  If you wish to look into testing your horse, you may use the list of all labs of which we know and the tests they are currently able to here, HERE.

These subjects are still under investigation:

1. Whatever gene(s) caused the color of the Royal Hanoverian Cream horses

2. "Light Black"

3. Disputed Dun (until the DNA test is developed)

4. "Light Classic": found in the Champagne color registry, possible offshoot of "light black"
