background: major histocompatibility complex (mhc) in chicken has profound influence on resistance/susceptibility to disease, and production and reproduction traits. microsatellite marker lei0258 is a genetic indicator for mhc haplotypes. recognizing diversity of mhc haplotypes in selectively bred populations will be helpful for selecting population resistant to disease and development of effec...

this study investigated genetic variation within indigenous chicken of khorasan using four microsatellite markers (mcw5, mcw16, mcw18 and mcw34). 90 blood samples were collected from this population and phenol-chloroform extraction method was used to isolate the dna. the highest and the lowest allele number and effective alleles are shown in mcw5 (6 and 5.293) and mcw34 (4 and 3.138), respectiv...

association of genetic polymorphism in the calpastatin (cast) gene with average daily gain was examined in iranian purebred kurdi sheep. the genotypes for cast were determined by the pcr-sscp method. blood samples were collected from 84 purebred kurdi sheep belonging to the kurdi breeding station located in the khorasan province, north-east of iran. extraction of genomic dna was based on the gu...

Association of genetic polymorphism in the calpastatin (CAST) gene with average daily gain was examined in Iranian purebred Kurdi sheep. The genotypes for CAST were determined by the PCR-SSCP method. Blood samples were collected from 84 purebred Kurdi sheep belonging to the Kurdi Breeding Station located in the Khorasan province, north-east of Iran. Extraction of genomic DNA was based on the Gu...

the aim of the present study was to assess the frequencies of angiotensin i-converting enzyme (ace; omim: 106180) and methylenetetrahydrofolate reductase (mthfr; omim: 607093) polymorphisms in the algerian population to further facilitate investigations on possible associations with various pathologies. the study was carried out on 146 apparently healthy individuals (65 males, 81 females) who w...

Hardy-Weinberg equilibrium (HWE) is the state of the genotypic frequency of two alleles of one autosomal gene locus after one discrete generation of random mating in an indefinitely large population: if the alleles are A and a with frequencies p and q(=1-p), then the equilibrium gene frequencies are simply p and q and the equilibrium genotypic frequencies for AA, Aa and aa are p2, 2pq and q2. I...

this study was carried out to investigate the genetic diversity and population structure of 90 specimens of oxynoemacheilus argyrogramma collected from sepidbarg, gamasiab and ghaleji rivers, in the west of iran. analyses using three microsatellite loci indicated that the average number of alleles in the population was 12, which was well above the reported values for freshwater fishes. the expe...
