Fourteen microsatellite markers were isolated from the giant red shrimp Aristaeomorpha foliacea (Risso, 1827) using the FIASCO protocol (fast isolation by AFLP of sequences containing repeats). Polymorphism was assessed in 30 individuals from two localities of the western Mediterranean basin (N = 20 from Sardinia and N = 10 from Sicily); nine loci showed polymorphism with 2 to 19 alleles p...

In bivalves, heterozygote deficiencies and departures from Hardy-Weinberg equilibrium (HWE) in microsatellite analysis are common and mainly attributed to inbreeding, genetic patchiness (Walhund effect), or null alleles. We checked for the occurrence of null alleles at 3 microsatellite loci in 3 populations of black-lipped pearl oyster, Pinctada margaritifera, using a step-by-step method to re-...

Testing genetic markers for Hardy-Weinberg equilibrium is an important issue in genetic association studies. The HardyWeinberg package offers the classical autosomal tests for equilibrium, functions for power computation and for the simulation of marker data under equilibrium and disequilibrium. Recently, specific frequentist and Bayesian tests for X-chromosomal markers have been developed and ...

UNLABELLED PREMISE OF THE STUDY Nuclear microsatellite (simple sequence repeat [SSR]) markers were developed for the woody species Leptospermum recurvum found on Mount Kinabalu, Borneo, to facilitate investigation of the genetic structure and patterns of gene flow in relation to leaf phenotypic polymorphisms. • METHODS AND RESULTS Eleven primer pairs were developed using the compound SSR m...

To assess the level and spatial pattern of genetic diversity of the common dormouse, Muscardinus avellanarius, we developed polymorphic microsatellite loci from partial genomic libraries enriched for microsatellite motifs. Ten dinucleotide polymorphic microsatellites were isolated and levels of genetic diversity were assessed in 139 individuals from Bontuchel, (Denbighshire, Wales). We observed...

This is the first in a series of 3 articles serving as an introduction to clinicians wishing to read and critically appraise genetic association studies. We summarize the key concepts in genetics that clinicians must understand to review these studies, including the structure of DNA, transcription and translation, patterns of inheritance, Hardy-Weinberg equilibrium, and linkage disequilibrium. ...

In the present study, thirty autosomal insertion and deletion polymorphic loci were simultaneously amplified and genotyped in a multiplex system, and their allelic frequencies as well as several forensic parameters were obtained in a sample of 236 unrelated healthy Tujia individuals. All the loci were in Hardy-Weinberg equilibrium after applying a Bonferroni correction and all pair-wise loci sh...

UNLABELLED PREMISE OF THE STUDY Microsatellite markers were isolated and characterized in Shorea platyclados (Dipterocarpaceae) for DNA profiling and genetic diversity assessment of this tropical timber species. • METHODS AND RESULTS Fifteen polymorphic microsatellite loci were developed and characterized in S. platyclados using a genomic library enriched for dinucleotide (CT) repeats. The...

Here we document the development of thirteen novel microsatellite markers for the reticulated glass frog Hyalinobatrachium valerioi (Centrolenidae). Nine of those markers were polymorphic and contained between 4 and 34 alleles per locus (mean = 20.3) in 138 individuals (91 males, 47 females) from the field site 'La Gamba', Costa Rica. Average observed heterozygosity was 0.76. Two loci (Hyval19 ...

UNLABELLED PREMISE OF THE STUDY Novel microsatellite markers were characterized in the wind-dispersed and dioecious neotropical tree Triplaris cumingiana (Polygonaceae) for use in understanding the ecological processes and genetic impacts of pollen- and seed-mediated gene flow in tropical forests. • METHODS AND RESULTS Sixty-two microsatellite primer pairs were screened, from which 12 mark...
