Have they discovered the dun gene marker yet? Either to just test for it (it's there) or whether it's homzygous or hetrozygous?
Am toying with testing my mobs genetic markers...red base, black base, agouti etc and have one of those black/grulla horses I would love to test for dun so I know once and for all.
I remember there was something posted that either they had found where the marker lives or found the gene and were either close or could now test for dun.
Anyone know?

UC Davis is offering a dun zygosity test. Here is the link: www.vgl.ucdavis.edu/services/horse.php I am not sure how acurate or aware of any recent break throughs on this topic but did see this when sending in hair samples for our new foal crop this year. edited to add: Here is an article put out by UC Davis explaining nore about the dun testing. The link is: www.vgl.ucdavis.edu/services/dunhorse.php |

I sent hair in to UC Davis for a Dun test on my Perlino Champagne stud colt. I was sure he was dun as you could see his stripe when he was born, but needed to be sure since I was selling him.  I believe for the dun, they also wanted to know his breeding with what colors the parents were. The results for him were D/N - Horse has one copy of the Dun gene. |

lwood:
How long did it take to get your results back? I am thinking about sending in Baby's hair for testing. That is our Red Dun / Sabino Kiger/Arab filly.

It only took a few days. They send the results to you through email and then also snail mail. If I remember right I got the email a day or two after they received the samples. It was very quick!

If your horse has a regular dun coat color this test should be very good. However, if it has the sooty gene it will not be. They look for the marker but also look at the parents' coat colors and markings. That tells me that they want to see a lightened coat color on at least one parent and on the foal before they will consider that it is dun, a common mistake and understandable since there are not many dun horses. They have trouble with dun in Spanish horses, presumably because so many are grey and they can't tell without coat color.
