I just got off the phone with DNA Diagnostics. She said the horse tests are done and the people who supplied an email address will get results today, and on-paper results will be mailed out tomorrow at the latest. She was actually working on my file when I called lol.

The good news is I got the results of a mininhorse today
The bad news is theyve lost the samples/results of the other mini horse , that was the one I really wanted too , Ive since sold the filly and it would be difficult t get more samples

I don't trust them ONE BIT Supa. Anything important I will have retested. They did get Lace's cream, and LWO right for sure. I'm also guessing they were right about champagne, tobiano and silver. :rofl But who knows about the agouti (the only thing I've considered retesting).

Rusti Wed, 03/17/2010 - 12:59

[quote="supaspot60"]when you realise how imcompetant they are it makes you wonder f you can trust the results they do give out ~x( Did you get your results Rusti ?[/quote]

Yup, I got my results after about 3.5 weeks (sent hair on 1-29, results via email on 2-24), and they were correct. Sorta. He's smokey brown but the results show him as buckskin since they don't test for brown. So not their fault. I guess I'm really lucky cause I had a wonderful experience with them, and they were always very polite and informative on the phone. I'm so sorry everybody else got the rough end of their dealings. If I test again it won't be with them.

I also went through this thread and removed all the extraneous "onclicks" That got added to links when the forum moved.

Threnody Fri, 08/05/2011 - 10:40

Absolutely random. But does anyone know if the Wiley article 7 Novel KIT Mutations shows images of animals with W6(TB) W7(TB) W8(Icelandic) W9(Holstein)and W11(South German Draft Horse?

EDIT: admin, this thread isn't showing up anywhere outside the latest post segment on the forums page for some reason.

Guess it just glitched with me temporarily, only the seal brown discussion was stickied when I looked before. Sorry for the false alarm and glad it fixed itself!

Question, has Pearl still not been published by Davis? How come Animal Genetics is able to offer the test? Did they also discover it shortly after or...?

This is a 2009 article so nothing new but I hadn't read it before. You have to register for a free account then to read the article.

Coat Color Variation at the Beginning of Horse Domestication

http://www.sciencemag.org/content/324/5…

The most interesting tidbit...

In contrast, a rapid and substantial increase in the number of coat colorations is found in both Siberia and East Europe beginning in the fifth millennium B.P. (Fig. 1 and figs. S1 and S2). Although the earliest chestnut allele (MC1R gene) was identified in a Romanian sample from the late seventh millennium B.P., chestnut horses were first observed in Siberia (fifth millenium B.P.). Their prevalence increased rapidly, reaching 28% during the Bronze Age.

Mutations responsible for coat color dilutions or spottings seem to appear later. Cream (buckskin) and (black) silver dilutions (2800 to 2600 yr B.P.) were first observed in Siberia. Sabino is the first spotting phenotype, appearing during the fifth millennium B.P. in Siberia, and present in Armenia and Moldavia during the middle Bronze Age. The Tobiano spotting was first found in a single Eastern European sample (3500 to 3000 yr B.P.) and later also in Asia. Unlike in samples from Siberia and Eastern Europe, we observed no color change in Spanish samples until medieval times.
