The colour locus historically referred to as C in the horse is linked to microsatellites markers on horse chromosome 21. Preliminary results demonstrated linkage of C cr , thought to be the cream dilution variant of the C locus, to HTG10 . An analysis of horse chromosome 21 using additional families confirmed and established a group of markers linked to C cr . This work also improved the resolution of previously reported linkage maps for this chromosome. Linkage analysis unambiguously produced the map order: SGCV16 ‐(19.1 cM)‐ HTG10‐ (3.8 cM)‐ LEX60/COR73‐ (1.3 cM)‐ COR68‐ (4.5 cM)‐ C cr ‐(11.9 cM)‐ LEX31 . Comparative and synteny data suggested that the horse C locus is not tyrosinase ( TYR ).
