Summary 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 c M in contrast to 117.8 c M for GS. The breed specific linkage maps show differences in length but confirmation of the order of the markers.
