The genetics of human populations is the branch Genetics that studies dynamics genes in natural populations, aiming at elucidation mechanisms alter their genetic composition. Among fundamentals this science Hardy-Weinberg Equilibrium, which determines gene frequencies remain unchanged and genotypic proportions reach a stable balance, obtaining same constant relation with each other over time. T...

background: molecular components of the dopamine receptor (drd3) play an important role in the pathophysiology of schizophrenia (scz). previous studies have demonstrated an association between the drd3 ser9gly polymorphism and scz but the results have been inconclusive. method: in this study, we investigated this controversial association between the ser9gly (a/g) polymorphism and scz using mal...

this study compares diversity patterns of five microsatellite (ssr) markers in two iranian native horse populations (turkoman sahra and turkoman jergelan) to infer relationships between them and to compare levels of their polymorphism for use in conservation efforts. two populations across microsatellite loci had significant deviations from hardy-weinberg equilibrium. average number of alleles ...

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 of makoei sheep was investigated by polymerase chain reaction and single strand conformation polymorphism technique (pcr–sscp). genomic dna was extracted from whole blood samples collected from 100 sheep. a 622 bp cast exon 1 segmen...
