Yeah I realized she is not a wild bay, I got confused there :p and no my friend tested him through a university genetics lab, it cost her 50$ and they sent the paper back saying something along the lines of dominant agouti
Etc therefore the horse is tested as bay. Ill see if I can get her to scan the test for me. I'm not sure what you mean by pet lab?

The generic agouti test seeks the recessive "a" allele. If they find two, then the horse is not carrying agouti, and is "a/a". If they find one, they get a result along the lines of "a/_", and if they don't find any, they get a "_/_". The labs then fill in the blanks with a dominant gene - "A". They haven't detected a dominant gene, just a lack of the recessive one. So while they can tell how many dominant genes are there through elimination, they can't tell what dominant gene it is.
Pet DNA of Arizona is a private lab. They are the lab that has isolated the gene responsible for brown, and are the only lab that tests for the dominant allele on the agouti locus.
