摘要:

SummaryCattle and water buffalo sera labelled with vitamin D3[14C] (300 and 480 individual samples respectively) were subjected to starch gel electrophoresis followed by autoradiography in an attempt to identify a possible polymorphism of the proteins capable of binding this vitamin.Three phenotypes controlled by two codominant autosomal alleles were identified in cattle while in water buffalo six phenotypes controlled by three codominant autosomal alleles were observed.

摘要:

SummaryIn 24 fish species of the Cyprinidae family, belonging to 21 genera, isoenzyme patterns of lactate dehydrogenase (LDH) were determined, which could be classified in the majority of cases into 3 main groups. Isoenzyme patterns in natural hybrids of roach and rudd, roach and bream, roach and bleak were also analysed. In bitterling, polymorphism was observed inBlocus of LDH. In white bream polymorphism exists in theAlocus. In bream, rudd, silver carp and barbel polymorphism was found in C loci. Isoenzyme patterns indicate that in each case the polymorphism is genetically controlled by two alleles at a single locus. The populations investigated were in Hardy‐Weinberg equilibrium. No significant differences were found in the activity of liver LDH in various polymorphic types of C loci of bream and rud

摘要:

SummaryThe hemopexin locus phenotypes were determined for 450 animals with polyacrylamide gel electrophoresis, and the presence of a fourth allele at this locus was revealed. Of the 19 mating types segregating at this locus, 17 demonstrated segregation ratios consistent with the hypothesis of a four allele, codominant, autosomal system. Studies of three of our largest inbreeding lines indicated that fixation at this locus has occurred in two of them. Linkage studies showed that theHxlocus is located between the color locus,c, and theHqblood group locus; therefore it is assigned to Linkage Group I of the rabbit.

摘要:

SummaryThree NADH diaphorase phenotypes were observed in the red cells of sheep. Breeding data indicated that this polymorphism was under the control of two autosomal co‐dominant alleles, designated DiaFand Dias. Phenotype Dia F had significantly lower NADH diaphorase activity than phenotype Dia S. The frzquency of DiaFand DiaSwas determined in 9 different breed

摘要:

SummaryFour Bovidae cell lines (BEK‐1, MDBK, Bu and EBTr) were characterized by means of enzymatic biochemical markers. Out of 15 enzymatic systems, 3 — adenosine dea‐minase [Ada), phosphoglucomutase (Pgm) and nucleoside phosphorylase (Np) —were found to be polymorphic and quite suitable for biochemical identification of each cell line. The Bu cell line has shown a Np phenotypic pattern which could be distinctive of theBison bison

摘要:

SummaryHemoglobin, non‐enzymatic and enzymatic muscle proteins of the loachCobitis delicatawere examined electrophoretically. Eleven proteins were shown to be under control by 20 loci. Only two loci were defined as polymorphic and 14 loci were completely monomorphic. Estimated average heterozygosity over all 20 loci was 0.011 in the loach populatio

摘要:

SummaryPhosphoglucomutase of two groups of the loachCobitis biwae, a fresh‐water teleost, was examined by starch gel electrophoresis. Some of the fishes had six‐banded electrophoretic patterns not observed in other loach species (e.g.Misgurnus anguillicaudatusandCobitis delicata). The complexity of the pattern is explainable by an assumption that the loaches are tetraploid fishes. The result suggests that a diploid‐tetraploid relationship exists within the speciesCobitis
