Imputation of Microsatellite Markers With Tag SNPs
<p>Of the two most common forms of genetic variation in the human genome, Single Nucleotide Polymorphisms (SNPs) and Variable Number Tandem Repeat Polymorphisms (VNTRs), SNPs are much more easily and inexpensively assayed in a high-throughput manner. For this reason, we seek to explore methods that …

Selection for Run1-Ren1 Dihybrid Grapevines Using Microsatellite Markers
… in a grapevine hybrid family using flanking microsatellite markers. Segregation of the powdery mildew resistance phenotype was evaluated under in vitro and greenhouse conditions independently of the genotype data. Combined analysis of phenotypic and genotypic segregations confirmed that Ren1 …

Evaluation of microsatellite markers for parentage verification in South Africa Angora goats
… and lead to increased selection accuracy. Microsatellite markers were evaluated for inclusion into a parentage verification panel, to be applied in the South African Angora goat population. The panel of 18 microsatellite markers was constructed, optimized and tested in 200 South African …

Development and Characterization of Microsatellite Markers for the Grain Amaranths (Amaranthus spp. L.)
… a set of highly informative, reproducible microsatellite markers for the grain amaranths. A total of 1457 clones were sequenced from three genomic libraries enriched for the microsatellite motifs AAC, AAT and AC. Of these, 353 (24%) contained unique microsatellites. An additional 29 …

A biogeographic analysis of the species Fragaria vesca using microsatellite markers on a worldwide plant collection
… 300 plants were analysed using 66 of the 68 microsatellite markers tested. Their mean allele number per locus was 3.94 and the mean polymorphic information content value was 0.13. Ten markers were monomorphic and 13 biallelic. The collection of plants was analysed using Beyasian clustering …

Isolation and characterization of microsatellite markers for human identification in the vhembe District, Limpopo Province, South Africa
… for isolating potentially polymorphic human microsatellite markers at a cheap and most convenient time. The designed human microsatellite markers were optimized for PCR amplification and used in genotyping a mini population of three major ethnic groups in the Limpopo province within in the …

The taxonomic and systematic relationships of several salt marsh Fucus taxa (Heterokontophyta, Phaeophyceae) within the Gulf of Maine and Ireland examined using microsatellite markers
<p>The present thesis utilizes microsatellite markers to examine genetic affinities between several salt marsh Fucus ecads in order to ascertain their relationships with attached parental species. Chapter I provides an introduction to the genus Fucus and discusses morphological plasticity, …

Genomic tools for the management of European flat oyster (Ostrea edulis) stocks
… have relied on a limited number of molecular markers. In an effort to expand our understanding of O. edulis genetic units and aid effective long term stock management, tissue sampled from over 1700 individuals representing the Atlantic coasts (with a focus on Irish coasts), Croatia and …

Population genetics of the farmland sawfly <em>Dolerus aeneus</em> (Hymenoptera, Symphyta)
… From this library, a set of 13 polymorphic microsatellite markers were isolated for use in the common farmland sawfly Dolerus aeneus. Using these markers, three Scottish populations of D. aeneus, a species common to all six UK sites sampled in this study, exhibited similar levels of genetic …

Genetic diversity and relationships among Nguni cattle populations in three Southern African countries
… Southern African region using a panel of 25 microsatellite markers, recommended by FAO and ISAG for genetic diversity studies. Genotypic data were generated from 90 unrelated autosomal DNA samples of the three cattle populations (SA Nguni n=30, Mozambican Nguni (Landim) n=30 and Swazi Nguni …

Comparative Analysis of Microsatellite and Mitochondrial Genetic Variation in <em>Ixodes Scapularis</em>
… utilizing nuclear and mitochondrial genetic markers have revealed the occurrence of two distinct lineages: a genetically diverse southern clade found in the southern-half of the distribution area of <em>I. scapularis</em>, and a more genetically homogeneous American clade found throughout the …

Movement Ecology and Conservation of the Migratory Bats Lasiurus cinereus and Lasionycteris noctivagans
… DNA control region and developed multilocus microsatellite markers to investigate the population genetics of hoary bats and silver-haired bats recovered at wind energy facilities in three Canadian provinces. Pairwise Fst values suggest subtle population-genetic structure among sites in both …

Mapping phenotypic traits in swine
… in the IMQP population was genotyped for 137 microsatellite markers and 43,486 single-nucleotide polymorphisms (SNP). Two different analyses were performed to detect QTL in this population. For the first analysis, a linkage map consisting of 137 microsatellite markers was used to perform a …

Genetic factors affecting establishment during invasions : the introduction of the topmouth gudgeon (Pseudorasbora parva) and the rainbow trout (Oncorhynchus mykiss) in Europe
… European waters. I used mitochondrial DNA and microsatellite markers to understand the invasion history of these species and the factors that influence their establishment success/failure. Part of the cytochrome b gene was analysed in European and native Asian P. parva populations and …

Conservation genetics of a spotted salamander (Ambystoma maculatum (Shaw 1802)) local population in southeast Tennessee
… Ambystoma maculatum (Shaw 1802) using thirteen microsatellite markers. Most loci exhibited no loss of heterozygosity but the low effective population size may indicate vulnerability to future declines. No population substructure or sex-biased dispersal was detected. Possible explanations for the …

Population abundance and genetic structure of black bears in coastal North Carolina and Virginia using noninvasive genetic techniques
… analyzed for individual identification using 6-7 microsatellite markers. Estimated densities were some of the highest reported in the literature and ranged from 0.56-0.63 bears/km2 at GDSNWR to 0.65-1.12 bears/km2 at ARNWR to 1.23-1.66 bears/km2 at PLNWR. Sex ratios were male-biased in all areas …

Identification and isolation of microsatellite loci from the Trematode Echinostoma Trivolvis for use in interspecific and intraspecific variation studies
… a significant impact on amphibian populations. Microsatellite markers were to be identified and isolated because of their highly variable nature and reported ease of use with PCR. Parasite DNA was extracted from planorbid snails from several locations within California including: Point Reyes …

Elucidating the conservation status of Michigan's red-eared slider (trachemys scripta elegans): A phylogeographic approach
… Indiana, Michigan, and Ohio, using six microsatellite markers. No isolation-by-distance was detected and model-based statistics support two genetic clusters with five populations from Michigan, Ohio, and Indiana forming one cluster and a single Michigan population forming a second. These …
