Re: [RC] [RC] Flaxen, Sabino gene - Soli SorokinSounds like she is a rabicano. She may have the sabino gene, but usually there is more white on the face with that. She does not carry the tobiano gene based on your description. Rabicano causes white hairs interspersed on the coat (and the coat is often, but not always, more "smutty" than the usual for whatever color the horse is). It also usually causes white on the tailhead and interspersed within the tail - anywhere from a few hairs to quite a few. I would not expect her to produce any significant pinto coloration in foals, but she may pass on the rabicano, or sabino if she does indeed carry it. Interestingly enough, the sabino that exists in TWH's and the one that exists in other horses, particularly arabians, seems significantly different in the possiblities for coat patterns. CMK arabians, which seem to have the greatest incidence of the Arab-type sabino, often have tall white socks and big blaze faces, often also having belly spots. But you never see a maximum-expressed sabino as you do with TWH lines that carry sabino. (This will be a foal born white, with some very minimal body spots of color). You also don't see the pseudo-tovero (tobiano-overo combination) colorations that sabino produces in TWH's but does not produce in Arabians. My guess is that these are two different genes that produce similar results and have therefore been named the same thing. I do not think there is a test for either sabino pattern. Here is a picture of a colorful sabino TWH stallion. He does not carry an overo or tobiano gene, and has sired everything from solid foals to foals with "Arab type" sabino to foals colored such as himself, out of solid mares. http://www.dawsonwalkers.com/ I did own a rabicano arab filly quite a few years ago. She was a liver chestnut, very dark, with white hairs on the flank and shoulder area and a white tailhead with a few white hairs through the tail. Her sire was black-bay and her dam was chestnut-gone-grey. Her sire was not rabicano so I presume it came from the mare, but as she was grey it was not visible. The filly actually had some black hairs in her coat and to simply look at her one would think she might have been a very sunburned black, but she was most definitely chestnut by genetic testing. ~S On 1/8/06, L gin <ladurgin@xxxxxxx> wrote: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Ridecamp is a service of Endurance Net, http://www.endurance.net.
