The status of the sheep map to the end of June 1993 is presented. Mapping information is available for a total of 107 loci comprising 16 anonymous DNA segments. This is an increase of 66 loci since 1990. No loci have been mapped on 10 of the 26 autosomes. Comparison of the cattle (350 loci) and sheep maps confirms their close evolutionary and genetic relationship and will reduce the effort required for their gene mapping.
