This information taken from the Paint Horse Journal, December 1998.
Minimally-expressed, the sabino pattern manifests itself in the form of white markings on the head and legs on an otherwise solid-colored horse. Sabinos are often confused with solid horses that have usual white markings. The sabinos are different in that their white marekings tend to have narrow, pointed extentions up the legs or down the throat. Minimally-marked red roan sabinos are often confused with classic roan horses, with the only difference being the sabino's extended leg and face markings. Sabinos are interesting for several reasons, not the least of which is the subtle and fascinating array of variants that the pattern can take. Sabinos range from quite solid, to very roaned or speckled, to very patched, and everything in between. Nearly all sabinos have white legs, a great deal of white on the head and white areas on the belly. These characteristics help seperate the sabinos from the more familiar tobianos and frame overos. Tobiano and frame overo are both caused by single genes. Horses either have the gene and are spotted, or don't have the gene and therefore lack the pattern. The only exception to the passage of these genes is the homozygous tobiano horse, which trasmits the tobiano gene to all its offspring. The sabino production records that have recently been made available now strongly suggest that the pattern is polygenic. This means that it comes about as the result of the action of several different genes, each of which make a small contribution to the overall pattern. Minimally-white sabinos simply have fewer of these genes than do maximally-white sabinos. The sabino pattern, whith all its variants, and obvious propensity to throw back to the patterns of previous generations, offers on the the most exciting and potentially rewarding tools to ever be placed at the disposal of the serious Paint breeder. |
