I went out and looked at the companies doing various Canine Genetic Tests (and I suspect this is a subset of the companies doing that) – Healthgene, Vetgen, DDC (DNA Diagnosis Center), Optigen, AHT (Animal Health Trust), and Genetic Technologies (who has a fascinating service where they offer DNA testing to prove whether a dog was responsible for a dog attack and will act as a professional witness in court based on the results – I think this is in Australia though).  None offered solid vs ticked testing in their color programs (many offer the black/liver analysis, and the “hidden” genes for orange, yellow, etc on the E locus).  So although the genetic technology is there to identify homozygous or not on a solid vs ticked gene – so as far as I can see no company has developed that test (probably not cost effective for them).  I think the best targeted color gene test is from Healthgene that is inclusive of the Wirehair, Shorthair, and Longhair German Pointers, which includes just the E and B gene pairs.

I’d be curious if someone knows of a company that does provide solid/ticked type of specific genetic gene identification?

You should check with Healthgene.  They have a genetic test for coat color.  It is primarily aimed at determining whether a dog has a "hidden" coat color, that is, an undesirable recessive such as red.  The "readout" you get from Healthgene does have the primary genes for coat color, i.e. BB or Bb or bb.  I don't remember if, or how much more, they can provide.  www.healthgene.com

I have a DNA question I thought one of the people on this list may be able to answer.  Does anyone know if the gene for coat pattern can been identified on the AKC's DNA certificate?

 

Specifically, I have several pups from here that have two solid liver parents. I wanted to see if we could tell from their DNA certificates if any of them are homozygous for solid coat pattern.  One bitch will likely be bred next year and I was wondering if an all solid litter should be expected.  I was hoping the DNA certificate could provide the info, but expect that is a false hope and we will have to wait and see what comes out.  If anyone knows the answer, I would appreciate it!
