Differences in recombination rates on chromosome 23 between German Angus and German Simmental and breed specific linkage mapping.
Five paternal half sib families of German Angus (GA) (n = 428) and six of German Simmental (GS) (n = 378) including dams were genotyped with 11 microsatellites (INRA132, RM033, BM1815, BM1258, BOLA-DRB1, BM1818, BM1905, BM1443, CYP21, CSSM5 and DYMS1) derived from chromosome 23. Differences in heterozygosity between the breeds were observed. Significant differences in recombination rates between GA and GS could be demonstrated for the marker intervals INRA132-CSSM5, CYP21-BOLA-DRB1 and BOLA-DRB1-BM1818. The length of the map of GA was 90.5 cM in contrast to 117.8 cM for GS. The breed specific linkage maps show differences in length but confirmation of the order of the markers.
