HFCs (heterozygosity-fitness correlations) measure the direct relationship between an individual's genetic diversity and fitness. The effects of parental heterozygosity and the environment on HFCs are currently under-researched. We investigated these in a high-density U.K. population of European badgers (Meles meles), using a multimodel capture-mark-recapture framework and 35 microsatellite loc...
Biallelic mutations in the NBS1 gene are responsible for the Nijmegen breakage syndrome (NBS), a rare autosomal recessive disorder characterized by chromosome instability and hypersensitivity to ionising radiation (IR). Epidemiological data evidence that the NBS1 gene can be considered a susceptibility factor for cancer development, as demonstrated by the fact that almost 40% of NBS patients ha...
BACKGROUND AND AIMS Despite the great importance of autopolyploidy in the evolution of angiosperms, relatively little attention has been devoted to autopolyploids in natural polyploid systems. Several hypotheses have been proposed to explain why autopolyploids are so common and successful, for example increased genetic diversity and heterozygosity and the transition towards selfing. However, ca...
Several studies have reported positive correlations between the degree of enzyme heterozygosity and fitness-related traits. Notable among these are the correlations between heterozygosity and growth rate in marine bivalves. Whether the correlation is the result of intrinsic functional differences between enzyme variants at the electrophoretic loci scored or arises from non-random genotypic asso...
Calpastatin (CAST) is a specific inhibiter of Calpains, playing a role in meat tenderization and myogenesis. In the present study the polymorphism of the CAST gene ofKhalkhali goat in Azerbaijan province in Iran was investigated by polymerase chain reaction and restriction fragment length polymorphism technique (PCR-RFLP). Genomic DNA was extracted from whole blood samples collected from 200 Kh...
