Technical Abstract: An autosomal genetic linkage map of the sheep genome has been generated from the segregation analysis of 231 polymorphic markers in nine three generation full-sib pedigrees which comprise the AgResearch International Mapping Flock. The markers used in the segregation analyses comprised 72 anonymous microsatellite markers from sheep, 126 anonymous microsatellites from cattle and 33 polymorphic gene markers. The number of meisoses within the mapping flock was 222. The average number of informative meioses per marker was 140. The map comprises 30 linkage groups and covers 2010 cM of the sheep genome. Linkage groups have been provisionally assigned to all the ovine autosomes based on at least one member of the group having been assigned to either a sheep or cattle chromosome.
