The endangered perennial plant Annamocarya sinensis (Dode) Leroy is a tertiary relict tree restricted to southeastern China and northern Vietnam. To explore endangerment mechanisms, develop protection strategies, and guide reintroduction efforts for this species, we investigated genetic diversity and population structure by surveying 70 individuals from three distinct populations using 12 polym...

Genetic markers are used for identity testing and paternity analysis depends on knowing the allele frequencies in the population. Minisatellites show allelic variability in the number of repeat units. We have studied the allele frequencies and heterozygosity of two VNTRs (ApoB and D1S80) in Iranian populations. A total of 96 and 82 chromosomes were analyzed by PCR and gel electrophoresis for Ap...

The wheat stem sawfly is an important insect pest of wheat that can cause significant damage to yield and grain quality. Five microsatellite loci were isolated and characterized in wheat stem sawfly, Cephus cinctus , to facilitate future population genetic studies and help delineate their geographical origin. These loci were found to be polymorphic with an expected heterozygosity ranging from 0...

Many asexual animal species are of hybrid origin, with consequent high levels of heterozygosity. Data from some studies suggest that increased heterozygosity may be functionally correlated with superior performance in a variety of fitness-related traits. Thus, hybrid asexual species could be expected to exhibit some degree of heterosis. This spontaneous heterosis hypothesis is tested in a compa...

assessing genetic biodiversity and population structure of minor populations through the information provided by neutral molecular markers, allows determination of their extinction risk and to design strategies for their management and conservation. analysis of microsatellite loci is known to be highly informative in the reconstruction of the historical processes underlying the evolution and di...

HERE have been several recent studies of the relationship between the heterozygosity of plant material and the magnitude of some quantitative character, usually yield or stability over a range of environments (YERMANOS and ALLARD 1961; FINLAY 1963; ROWE and ANDREW 1964). In each of these studies, single crosses and their derivatives have been used as the experimental material so that estimation...

The whole genome resequencing was used to develop single nucleotide polymorphisms (SNP) markers for the yellow catfish (Tachysurus fulvidraco). A total of 46 SNP from 129 individuals were selected 5550676 genotyping which distributed on 26 chromosomes. Of SNPs analyzed, 35 conformed Hardy-Weinberg equilibrium. observed and expected heterozygosity these ranged 0.2519 0.771 0.265 0.5018, respecti...

Four cattle breeds (Gyr, Nellore, Guzerat and Holstein) were analyzed by amplification of genomic DNA using microsatellite loci to evaluate the genetic diversity within and among them. DNA samples of 18 animals from each breed were collected to access the genetic content of them. Allele frequencies were calculated and used to generate a Nei’s genetic distance matrix what was used to build a den...
