genetic diversity is one of the three levels of biodiversity. the aim of present study was to compare levels of genetic polymorphism between wild bream populations using seven microsatellite loci. genetic diversity was investigated by studying samples collected from two regions, the coast of chamkhale and bandaranzali of gilan province. a total of seven microsatellite loci (mfw7, mfw26, mcs1eh,...

OBJECTIVE To study the associations of tumor necrosis factor (TNF) a, b and c microsatellite markers with 1) the clinical disease activity and 2) the induction of remissions in patients with early rheumatoid arthritis (RA) treated with two treatment strategies. METHODS In the FIN-RACo (FINnish Rheumatoid Arthritis Combination therapy) trial of two years, 195 patients with recent-onset RA were...

Although previous studies have failed to detect an association between microsatellite polymorphism and broadscale recombination rates in the human genome, there are several possible reasons why such a relationship could exist. For instance, there might be a direct link if recombination is mutagenic to microsatellite sequences or if polymorphic microsatellites act as recombination signals. Alter...

Microsatellite loci play an important role as markers for identi cation, disease gene mapping and evolutionary studies. Mutation rate, which is of fundamental importance, can be obtained from interspecies comparisons, which however are subject to ascertainment bias. This bias arises for example when a locus is selected based on its large allele size in one species (cognate species 1), in which ...

Although they represent powerful genetic markers in many fields of biology, microsatellites have been isolated in few fungal species. The aim of this study was to assess whether obtaining microsatellite markers with an acceptable level of polymorphism is generally harder from fungi than in other organisms. We therefore surveyed the number, nature and polymorphism level of published microsatelli...

Microsatellite markers containing simple sequence repeats (SSRs) are a valuable tool for genetic analysis. Our objective was to identify microsatellite markers that could be used to differentiate between male and female date palm (Phoenix dactylifera). The date palm is a dioecious plant whose sex cannot be determined until it reaches a reproductive age between 5 and 10 years. An early selection...

Linkage disequilibrium (LD) is bases of genomic selection, genomic marker imputation, marker assisted selection (MAS), quantitative trait loci (QTL) mapping, parentage testing and whole genome association studies. The Particular alleles at closed loci have a tendency to be co-inherited. In linked loci this pattern leads to association between alleles in population which is known as LD. Two metr...

Bream (Abramis brama orientalis) is one of the most commercially valuable fish in the Caspian Sea. The aim of this study was to compare levels of genetic polymorphism between wild and farmed Bream populations using seven microsatellite loci. Genetic diversity was investigated by studying samples collected from two regions; Chaboksar and the Artificial Propagation Center of Guilan province. Alle...
