| Abstract: | A two-point linkage analysis was performed between blood group (14), allotype (8), polymorphic protein (11), DNA type I (2), and microsatellite (2) loci in Wild Boar x Pietrain and Meishan x Pietrain three-generation families. The following new pairwise linkages were detected: LPR-EAN (Zmax= 60.68, Ø= 0.055), EAD-GH1 (Zmax= 17.43, Ø= 0.246), EAO—P3 (Zmax= 15.81, Ø= 0.239), and P3—S0003 (Zmax= 5.43, Ø= 0.312). This study and published mapping data enabled the localization of LPR (LPR allotype) to chromosome 9, EAD (erythrocyte antigen D) to chromosome 12, and EAO (erythrocyte antigen O) and P3 (P3 allotype) to the q arm of chromosome 6 with gene order SOOO3—P3—EAO, EAO being the most distal. |
