SummaryPhosphoglucose isomerase was analysed by electrophoresis in approximately 280Pecten maximusindividuals from two populations. Observed heterozygosity decreased with increasing dorso‐ventral valve length in both populations. The regression of heterozygosity on length in mm yielded the relationship H0= 1.119–0.003 L. Observed heterozygosity was very high in samples of small individuals indicating that self fertilization cannot be a regular feature of reproduction in this functional hermaphroditic species. Some possible causes for the observed decline in heterozygosity among larger individuals are discus

摘要:

SummaryGenetic polymorphism of hemoglobin was found in the erythrocytes of dogs of seven Japanese native breeds by using starch gel electrophoresis. Analysis of parentage records of the dogs revealed that the phenotypic variation of hemoglobin is controlled by one autosomal locus with two codominant alleles, HbAand HbB. The allele HbAoccurred only in Japanese native breeds except Shikoku. The frequency of HbAin the Japanese breeds was low and 0.08. All the dogs belonging to 25 European breeds and 5 oriental origin (except Japan) breeds examined in this experiments had the homozygous genotype constitution HbB/HbB.

摘要:

Summary1Twenty‐six strains of mice were surveyed by starch gel electrophoresis for genetic variation of four liver enzymes; aldehyde dehydrogenase, aldehyde oxidase, xanthine oxidase and formaldehyde dehydrogenase.2A variant of aldehyde dehydrogenase was found in strains ICFW, IS/Cam, NZB, NZW, Simpson and Schneider. A variant of aldehyde oxidase was found in CE. A possible variant of xanthine oxidase was found in SF/Cam.3The gene determining the electrophoretic variant of aldehyde oxidase is either the same as, or very closely linked to, theAoxgene which determines aldehyde oxidase activit

摘要:

SummaryA family study of an index case in the Arabian breed of horses demonstrated the presence of a new allele in the prealbumin (Pr) system of electrophoretically determined markers in horse serum which, when homozygous, results in the absence of any recognizable zones in the Pr region. The symbolPris proposed for this allele which has an estimated frequency in Arabian horses of 0.09.

摘要:

SummaryThis paper describes two allotypes of water buffaIo controlled by two codominant allelic genes. The third allele is a null allele and behaves as a recessive one. The two detectable serum antigens are termed A1 and A2 aild the third one (as yet undetectable) A0. The A1 antigen was recovered in the third peak and A2 antigen in the first peak following gel filtration through Sephadex G‐200. The A1 antigen is common to water buffalo and cattle; the frequency of the corresponding gene (A1) was the same in both specie

摘要:

SummaryAmong 11 lymphocyte factors defined in sheep, 9 are the products of multiple alleles at 2 closely linked loci: OLA‐A and OLA‐B. A tenth factor is the product of a gene at a third locus: OL‐X probably on the same chromosome, but in this case very distant from OLA. The last factor is the product of a gene at a fourth locus: OL‐Z, independent of OLA

摘要:

SummaryPolymorphism of equine Gc protein was demonstrated by immunofixation electrophoresis with a goat anti‐human Gc antibody. Three different phenotypes, F, FS and S, were found. Family data supported the genetic theory of two autosomal co‐dominant alleles, GcFand GcS. Both alleles occurred in Standardbred, Thoroughbred and Arabian horses and in Shetland ponies. A frequency of 0.23 for GcSin the American Standardbred horse indicates the system should be useful for problems of identification and parent
