SummaryElectrophoretic variation in glucose phosphate isomerase was found inN. alexis, N. cervinusandN. fuscus.Inheritance was apparently Mendelian with two co‐dominant alleles; heterozygotes possessed a triple‐banded phenotype. High intra‐specific electrophoretic variability was found in all species for transferrin. Most of the variation was attributable to variation in the number of attached moieties, probably sialic acid. InN. alexishowever, a second pattern of transferrin variation was found that followed a Mendelian pattern of codominant inheritance. In all four species, considerable variability was found in three zones of esterase activity, but the pattern of inheritance was not eluci

摘要:

SummaryThis report provides information on biochemical variants found in 17 species. These variants may be useful in answering some of the questions facing fisheries agencies concerning stock separation, hybridization, and life histories. Further studies should provide useful information in the areas of population biology of fishes in Alaskan waters.

摘要:

SummaryIn this paper family studies are presented which support the hypothesis of polymorphism in the process controlling sialic acid binding to bovine transferrin which modifies its phenotype as seen in starch gel electrophoresis. It has been shown that this polymorphism is controlled by a locus Tfs with two allelesTfs AandTfs a. Tfs a/aanimals have the abnormal phenotype with the two faster bands of the four bands of a normal transferrin allele being virtually absent.Tfs A/aandTfs A/Aare phenotypically normal. Limited evidence is presented which suggests that the Tf and Tfs loci are not linked.

摘要:

Summary1. The inherited differential agglutinability of cattle erythrocytes is shown to be similarly expressed on ghosts and intact cells.2. Removal of virtually all sialic acid by prolonged neuraminidase treatment does not alter the agglutinability status of ghosts prepared from either high or low agglutinable cells. Hence the differing sialic acid content of the two cell types is not responsible for the differential agglutinability.3. The significance of these findings with respect to other well defined agglutination systems and current theories of membrane structure is discussed.

摘要:

SummaryA genetic control of alkaline phosphatase (AP) in chicken duodenum was studied in a White Plymouth Rock strain. Unpurified chicken duodenum AP heated in an extraction procedure comprised either F or S band by isozyme types. On the other hand, chromatographically purified intestinal AP (NBCo, USA) had three bands, i.e., F', S' and B' bands. Characterization by urea, heat and neuraminidase treatments suggested that the genetic control of plasma AP isozymes may be applicable to the duodenum AP isozymes.

摘要:

SummaryGene frequencies of blood groups at 6 loci were estimated within two Dutch breeds of swine, Dutch Landrace and Dutch Large White. At all loci there were significant differences between breeds. The relationship of the two breeds with, respectively, the German Landrace breed and the German Large White breed could be confirmed by the gene frequencies.

摘要:

SummaryA new reagent called G‐3′ has been discovered which detects the product of theG3allele, regardless of the otherGallele in the genotype. With this new reagent we can delineate nine of 10 genotypes of theGblood group system. The explicit detection ofG3revealed an example of the founder principle in that the frequency of this allele between the feral and laboratory‐reared monkeys was significantly diff
