Detailed description
Tan-points originate genetically from the at-allel at the A-locus. The appearance of those marks can vary in some breeds. Large black areas with small tan-points are called black&tan, while the occurrence of large bright areas with a black saddle on the dogs back is called saddle-tan accordingly. This difference can be determined genetically in Welsh Corgi and Basset Hound. The causative allel for saddle-tan, which was found in wolves as well, is dominant to the recessive duplication, that is responsible for black&tan. Therefore, saddle-tan dogs can exhibit +/+ and +/dup as their genotype, black&tan dogs are dup/dup always.
