“…In contrast to conclusions of Oldenbroek & Bouw (1974), who considered the F and the N′ systems as a common blood group system F, the F system that consists hereafter of the antigenic factors F, V and N′, was divided according to Rasmusen (1975) and Schmid & Buschmann (1985) and denoted as FV and N′ systems and treated as two separate blood group systems. Apart from that, the FV blood group system also was separated with respect to the antibody–antigen reaction into the antigenic factor F and the antigenic factor V, hereafter called AFF and AFV, respectively.…”

Genes determining the bovine erythrocyte antigens were mapped by linkage analysis. In total 9591 genotypes of 20 grandsire families with 1074 sires from a grand-daughter design were elucidated for the genes determining the erythrocyte antigens EAA, EAB, EAC, EAF, EAJ, EAL, EAM, EAN', EAR', EAS, EAT', and EAZ according to standard paternity testing procedures in the blood typing laboratories. Linkage analyses were performed with 248 microsatellite markers, eight SSCP markers and four polymorphic proteins and enzymes covering the 29 autosomes and the pseudoautosomal region of the sex chromosomes. The number of informative meioses for the blood group systems ranged from 76 to 947. Blood group systems EAM and EAT' were non-informative. Most of the erythrocyte antigen loci showed significant linkage to a single chromosome and were mapped unequivocally. The genes determining erythrocyte antigen EAA, EAB, EAC, EAL, and EAS were mapped to chromosomes 15, 12, 18, 3, and 21, respectively. Lod-score values ranged from 11.43 to 107.83. Moreover, the EAF system could be mapped to chromosome 17. However, the EAN' system previously known as part of the EAF system could be mapped to chromosome 5. In addition, the blood group systems EAJ, the new EAN', EAR', and EAZ, showed significant linkage to microsatellite markers on various chromosomes and also to other blood groups. The appearance of a single blood group system might be therefore either dependent on the existence of other blood group systems or because of an interaction between different loci on various chromosomes as is known in humans and in pigs.

“…The results display that for the complex blood group systems out of many cattle haplotypes (R asmusen 1975) only a few exceed a frequency of 0.02. Such dominating haplotypes, which were also demonstrated in mice and humans (S vejgaard et al 1975), indicate the history of a population as well as the agents through which gene frequencies can change.…”

Summary With the help of blood group data the time depending changes of alleles are given for 1786 German Friesian sires which were blood‐typed from 1956 to 1982. Frequencies of alleles and haplotypes were calculated using blood group factors of the systems A, B, C, F, J, L, M, S, Z, and R′. Depending on the system the frequencies changed during the time interval differently in extent and direction. For the complex systems out of many haplotypes only few reached a frequency of ≥ 0.02. The frequencies and their changing give information about the historical development of a population as well as the factors influencing the population structure. Possible causes and practical meaning of the results are discussed. Résumé Fréquences des allèles et des haplotypes des taureaux de race German Friesian pendant les dernières décennies La distribution des allèles de 1786 pères de race German Friesian a été démontrée à l'aide des dates des groupes sanguins. Les taureaux ont été examinés sur leurs type sanguin pendant les années 1956 à 1982. Les fréquences sont dérivées des systèmes des groupes sanguins A, B, C, F, J, L, M, S, Z et R′. Selon les systèmes, les fréquences variaient au courant du temps de façon différente. Eu égard aux systèmes complexes des groupes sanguins, uniquement peu de haplotypes obtenaient une fréquence de ≥ 0,02. Les fréquences et leurs changements donnent des renseignements sur le développement historique d'une population ainsi que sur les facteurs influençants la structure de la population. Les causes possibles et la signification pratique des résultats sont discutées. Resumen Frecuencias Alélicas y Haplotípicas de Toros de la Raza Holstein Friesian Alemana durante las últimas decadas Se entregan las frecuencias alélicas de los grupos sanguineos de 1786 toros de la raza. H. Friesian Alemana, examinados entre los anos 1956 y 1982. Las frecuencias alélicas y haplotípicas de los grupos sanguineos fueron determinadas según los sistemas A, B, C, F, J, L, M, S, Z y R′. Segün el sistema empleado las frecuencias varian de acuerdo al tiempo. De los Complejos Sistemas de grupos sanguineos, de los muchos haplotipos, soló pocos alcanzaron una frecuencia ≥ 0.02. Las frecuencias y sus cambios dan información de la evolución hístorica de la raza y también sobre factores que influyen en la estructura de esa población. Son discutidas las causas posibles y el significado práctico de los resultados. Zusammenfassung Allel‐ und Haplotypfrequenzen bei Bullen der Rasse Deutsche Schwarzbunte während der letzten Jahrzehnte Anhand von Blutgruppendaten wurde die zeitabhängige Allelverteilung bei 1786 Vatertieren der Rasse Deutsche Schwarzbunte dargestellt. Die Bullen waren während der Jahre 1956 bis 1982 auf ihren Bluttyp untersucht worden. Die Allel‐ und Haplotypfrequenzen wurden unter Verwendung von Blutgruppenfaktoren der Systeme A, B, C, F, J, L, M, S, Z und R′ berechnet.

“…In the past, considerable attention has also been paid to the study of porcine blood groups. Up to now, over seventy reagents detecting antigens controlled by fifteen loci (designated A to 0) have been prepared (Rasmusen, 1975). Unlike the situation in man, the products of some blood group loci, e.g.…”

SUMMARY An alloantigen segregating in the double back‐cross families, distinct from serologically determinable transplantation antigens controlled by the major histocompatibility complex (SLA), was detected in pigs by the complementdependent lymphocytotoxic technique. The system was designated SLB and its product (antigen SLB‐Al) was demonstrated in all lymphocytes from the lymph nodes, thymus and peripheral blood, but not in the erythrocytes. Back‐cross matings supplied evidence of the dominant heredity of SLB‐Al. Detection of further SLB antigens was unsuccessful, so that only two alleles (SLB‐Al and SLB‐A‐) could be determined in families. Double back‐cross families revealed a close linkage between the SLB locus and the L blood group locus. Maximum lod score values were calculated in recombination fraction θ= 0.10.
