CHESTNUT FRIESIANS or "FOX" FRIESIANS

The genetic's of Chestnut/red factors is fairly simple to understand. Here are the factors tested for: 'ee' Only the red factor detected. The horse tested homozygous for red pigment. The basic color is chestnut or sorrel, but depending on genes at other color loci, the horse could be red dun, palomino, cremello, gray or white. 'Ee' Both black and red factors detected. The horse tested heterozygous for the red factor. It can transmit either E or e to its offspring. The basic color of the horse will be black, bay or brown, but depending on genes at other color loci, the horse may be buckskin, zebra dun, grullo, perlino, gray, or white. 'EE' Only the black factor detected. The horse tested homozygous for black pigment. It cannot have red foals regardless of the color of the mate. The basic color of the horse will be black, bay or brown, but depending on genes at other color loci, the horse may be buckskin, zebra dun, grullo, perlino, gray or white. Some Friesians Carry the Chestnut gene, the Ee that can produce a black or chestnut. Stallions that are known to carry this chestnut Gene are: Freark 218 Ijsbrand 238 Laes 278 Diedert 288 Jillis 301 Wicher 334 Atse 342 Abe 346 if you have a mare or colt sired by one of the above stallion's and would like to have your horse tested for the red factor you can send some hair with roots attached to Avian Biotech the cost is $25.00 and you get results back quickly. www.avianbiotech.com CHESTNUTS AND THE REGISTRY, Chestnut foals out of two registered Friesian Parents CAN be registered they just remain in the foalbook. However if you have a chestnut that then produces a black from an approved stallion that offspring can go back into the registry, try for ster etc.
