Canadian isolates of Leptosphaeria maculans, the causal agent of blackleg of crucifers, were examined for genetic relatedness by the random amplified polymorphic DNA assay. DNA polymorphisms amplified with random decamer primers were used to distinguish three groups of isolates. Group 1 contained all isolates of the virulent pathotype, group 2 contained isolates of the avirulent pathotype from ...

Characterizing patterns of genetic variation within and among human populations is important for understanding human evolutionary history and for careful design of medical genetic studies. Here, we analyze patterns of variation across 443,434 single nucleotide polymorphisms (SNPs) genotyped in 3845 individuals from four continental regions. This unique resource allows us to illuminate patterns ...

This study reports the isolation and polymorphism characterization of four plastid indels and six nuclear microsatellite loci in the invasive plant Heracleum mantegazzianum . These markers were tested in 27 individuals from two distant H. mantegazzianum populations. Plastid indels revealed the presence of five chlorotypes while five nuclear microsatellite loci rendered polymorphism. Application...

There is a rich population genetics theory on tests for whether an observed pattern of polymorphism, or an observed between-species difference (or both) can be accounted for with a standard drift model. Rejection of this hypothesis offers the possibility that selection may play a role, but (as we will see) other forces (such as population history) can also cause strong deviations from the neutr...

Pedigree information and phenotypic records are the key features in animal genetics and breeding. Otherwise best methods for genetic evaluation and estimation of parameters will be tending to no correct results. This study was aimed to investigate and verify pedigree relations among 76 individuals who were genotyped for 3 fluorescent labeled microsatellite markers picked up from FAO-ISAG joint ...

Background: Polymorphisms in the immune related genes are important in the clinical outcome of Helicobacter pylori infection. Myeloperoxidase -463 G/A polymorphism has been shown to reduce enzyme expression and activity. Objective: the aim of the present study is to investigate the association of myeloperoxidase G-463A polymor-phism with clinical outcome of Helicobacter pylori infection. Method...

MOTIVATION The current tendency in molecular population genetics is to use increasing numbers of genes in the analysis. Here I describe a program for handling and population genetic analysis of DNA polymorphism data collected from multiple genes. The program includes a sequence/alignment editor and an internal relational database that simplify the preparation and manipulation of multigenic DNA ...
