Variation in lipid synthesis, but genetic homogeneity, amongLeptopilinaparasitic wasp populations

Genetic Variation Within PoPulations

Seven microsatellite loci were used to develop multilocus genotypes for 49 individuals of Neotoma stephensi (Stephen’s woodrat) collected from nine sites in central and northern Arizona. Several statistical analyses were used to determine genetic structure, levels of genetic variability, and degree of relatedness. Structure analyses estimated two distinct groups within localities. The FST value...

Genetic variation in natural populations

Development of Microsatellite Markers and Detection of Genetic Variation between Goniozus Wasp Populations

Molecular genetic markers reveal differences between genotypes according to the presence of alleles (the same or different) at target loci. Microsatellite markers are especially useful co-dominant markers that have been used in a wide range of studies to elucidate the population structure and dynamics of a range of organisms, including agriculturally beneficial insects such as parasitic wasps (...

Genetic Variation and Inheritance of Early Growth Characteristics in Three Wild Pistachio Populations

Pistacia atlantica is the most important tree species for the economy of many rural areas in west of Iran, but no effort has been made for the genetic improvement of this species. The aim of this investigation was to study the genetic variation and inheritance of early growth traits in P. atlantica. For this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...

Genetic variation in cultivated Rheum tanguticum populations

To examine whether cultivation reduced genetic variation in the important Chinese medicinal plant Rheum tanguticum, the levels and distribution of genetic variation were investigated using ISSR markers. Fifty-eight R. tanguticum individuals from five cultivated populations were studied. Thirteen primers were used and a total of 320 DNA bands were scored. High levels of genetic diversity were de...
