Genetic Variation in Fish 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

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...

Genetic variation of Garra rufa fish in Kermanshah and Bushehr provinces, Iran, using SSR microsatellite markers

Six highly variable microsatellite loci were used to investigate the genetic diversity and population structure of the Garra rufa in Kermanshah and Bushehr provinces, Iran. All of the 6 microsatellite loci screened in this study showed polymorphism. A total of 90 individual fish from 3 populations were genotyped and 60 alleles were observed in all loci. The number of alleles per locus ranged fr...
