Breaking news We had Mr Good Jeans DNA test for color through Animal Genetics who came back Aa Ee, well from reading info on UC Davis website Mr Good Jeans shouldnt have black anywhere but mane, tail, tips of ears, lower part of legs. I copied from their website and have pasted below. Once we have the funds well be retesting. Agouti (Bay/Black) The Agouti gene controls the distribution of black pigment. The dominant allele A restricts black pigment to the points of the horse (mane, tail, lower legs and ear rims), as seen, for example, in bays and buckskins. The recessive allele a uniformly distributes black pigment over the entire body. Breeders interested in producing black horses need to have breeding stock carrying the a allele, in addition to the E allele of the Extension gene. Using results from the red factor and agouti tests, click here for a table of breeding schemes to produce black animals. Agouti results are reported as: A/A or A/a Black pigment distributed in point pattern. The basic color of the horse will be bay or brown in the absence of other modifying genes. A has no effect on red pigment (ee). a Only recessive allele detected. Black pigment distributed uniformly. The basic color of the horse will be black in the absence of other modifying genes.
