✦ Synopsis
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).
