Citaat:6/12/10: We have changed the calculator to take into account that Roan, Tobiano and Sabino are mutations of the KIT gene found on horse chromosome 3 and thus will not occur on the same branch of a horses chromosome pair. This means that a horse that carries any two of the Roan, Tobiano or Sabino genes can only be heterozygous for each gene and will pass one or the other to its offspring and never both or none. This also means a horse cannot carry more than two different KIT mutations or be homozygous for any if two of the genes are present.
In the future, we also plan to have the calculator consider linkage between KIT mutations and the Extension (Red/Black Factor) gene which is also found on horse chromosome 3
