摘要:

SummaryBiochemical polymorphisms (haemoglobin, serum transferrin, serum albumin, serum amylase, red cell phosphohexose isomerase, red cell carbonic anhydrase, ceruloplasmin and aryl esterase) of 224 Hungarian Native female goats and 21 imported male goats (German Improved, Saanen, Nubian, Slovakian White) have been studied.On the basis of the observed gene frequency values these polymorphic traits cannot be used efficiently in parentage control work or in correlation studies. There was no apparent association between the haemoglobin and transferrin type of the females and their reproductive performance.

摘要:

SummaryThis paper reports genetic variation at the prealbumin (Pr), postalbumin (Pa) and transferrin (Tf) loci inEquus przewalskiifound using thin layer isoelectric focusing and an amphoteric separator. The method resolves all three loci plus serum esterase (Es) on a single gel, and typing of all four loci is readily achieved. In addition to the esterase alleles previously reported by Fisher&Scott (1979), five alleles were found at thePrlocus. three at thePalocus and six at theTflocus. Analysis of several mating types confirms inheritance is autosomal and codominant for all four loci.

摘要:

SummaryGenetic distances between seven Dutch rare breeds of sheep were established as based upon blood groups and biochemical polymorphisms, A rather close relationship was observed between three breeds of heath sheep (Drente, Veluwe and Kempen) and the Schoonebeker sheep, The Mergelland sheep was less related to this cluster, The largest distances were between Friesian sheep and Black Blaze sheep and all others.

摘要:

SummaryTwo‐dimensional agarose gel (pH 5.4)‐polyacrylamide gel (pH 9.0) electropho‐resis of pig serum samples revealed a new serum protein (postalbumin‐2, PO‐2) polymorphism. Family data supported the hypothesis that the three PO‐2 phenotypes observed were controlled by two codominant, autosomal alleles (Po‐2FandPo‐2S) at a single locus. The frequency ofPo‐2Fin Swedish Landrace and in Swedish Yorkshire breeds was estimated at 0.74 and 0.65, respectively. Evidence was presented for close genetic linkage betweenPo‐2and the red cell phospho‐hexose isomerase locus (Phi). A recombination frequency of 3.2 % was obtained from double backcross material. Data obtained in a Danish Landrace material showing linkage between thePo‐2locus and theHblood group locus, thePgdlocus andHal(locus for halothane sensitivity) are also given. A total of seven re‐combinants were observed. They show thatPo‐2is a new locus in a previously established linkage group. The likely sequence of the loci i

摘要:

SummaryThe linkage group formed by the ELA and A blood group system in horses was studied in American Standardbred horses. The distance between the ELA locus and the A blood group locus was measured as 1.61 centimorgans. observing only the haplotypes contributed by the sires.Strong linkage disequilibrium was found in pacing Standardbred horses for ELA‐W1 with Aa, ELA‐W5 with Ab and ELA‐W10 with Ab. Linkage disequilibrium was apparent at both the population and family level. Among trotting Standardbred horses, linkage disequilibrium was found for ELA‐W1 with Aa and for ELA‐W10 with Ab. It was not possible to investigate linkage relationships in Thoroughbred horses because of the high frequency of Aa and low frequency of other A syste

摘要:

SummaryGenetic linkage between the equine loci for phosphohexose isomerase (PHI) and serum Xk protein was demonstrated by means of segregation data from three sire families. The recombination frequency was estimated from pooled data to be 0.23 ± 0.02; a significant heterogeneity between sires for estimates of the recombination frequency was observed. No indication of linkage was detected betweenXkand 14 other blood marker loci. Linkage between theXklocus and the locus for soluble malic enzyme (ME1) has recently been reported in horses. An equine linkage group designated LG IV comprising the three lociME1, PH1, andXkhas thus been established. The possibility that the linkage betweenPH1andXkis homologous to the linkage between the loci for PHI and a serum postalbumin (PO‐2) in pigs was discuss

摘要:

SummaryTotal serum haemolytic complement (HC) activity has been determined in 130 young bulls of the Norwegian Red Cattle Breed (NRF). A highly significant sire effect (p<0.01) on HC with a corresponding heritability of about 0.75 was estimated. Evidence of any simple mode of inheritance is not produced but the distribution patterns of HC indicate influences of relatively few genes.
