We developed 15 new polymorphic microsatellites for the plethodontid salamander Ensatina eschscholtzii. Loci were isolated from a genomic library from Ensatina eschscholtzii xanthoptica enriched for (AAAG)(n) repetitive elements. The number of alleles per locus ranged from 4 to 20 (mean 9) in the sampled population. Observed heterozygosity ranged from 0.37 to 1. None of the loci deviated from H...

We isolated 16 polymorphic microsatellite loci in the mountain pine beetle (Dendroctonus ponderosae Hopkins) and developed conditions for amplifying these markers in four multiplex reactions. Three to 14 alleles were detected per locus across two sampled populations. Observed and expected heterozygosities ranged from 0.000 to 0.902 and from 0.100 to 0.830, respectively. Three loci deviated from...

The genotypes of 31 autosomal short tandem repeat loci in the population of Carloforte were analyzed, these representing a linguistic and genetic isolate located on the island of Sardinia (Italy). The markers span the entire length of chromosomes 19, 20, 21 and 22. Allele frequencies and statistical parameters were presented for all loci. Observed heterozygosity ranged from 0.279 to 0.884, and ...

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...

We developed nine polymorphic microsatellite markers for the Mexican spadefoot toad, Spea multiplicata. Allele numbers range from five to 12, with observed heterozygosities from 0.48 to 0.87. Because two loci are in linkage disequilibrium, these nine loci provide eight independent markers. Three loci exhibit departure from Hardy-Weinberg equilibrium, possibly resulting from null alleles or popu...

OBJECTIVE To systematically investigate the role of matrix metalloproteinase-2 (MMP2) tagging single nucleotide polymorphisms (SNPs) and promoter functional polymorphism in the development of nasal polyps in a Chinese population in Taiwan. DESIGN We conducted a case-control study in 136 cases of chronic rhinosinusitis with bilateral nasal polyps and 136 controls. Seventeen SNPs were selected,...

The polymorphic variants of CYP1A1 and the deletion GSTM1 are present in Peruvian mestizo population. Wild type mutated genotypes (WT/*2A *2A/ *2A) were identified, whose allele frequencies 0.31 (T allele) 0.69 (C allele), respectively; 53% with wild (+) 47% null . frequency Iquiteño emigrants was 0.72 CYP1A1*2A 25% (-); from Lima 0.67 33% (-). Hardy-Weinberg equilibrium test for studied popula...

the major histocompatibility complex (mhc) genes are the most polymorphic loci in the human genome and have been widely studied in various populations and ethnic groups. investigations into the hla genes and proteins have been useful tool for anthropological, transplantation and disease association studies. the polymorphism of the hla class i (a, b, c) and class ii (drb1, dqa1, dqb1) genes were...
