For the present study, blood samples from 35 Murrah dam-progeny pairs and semen samples of their sires were collected. All six primers successfully amplified the genomic DNA from all the animals. The mean observed heterozygosity (Ho) within the population was found to be 0.5438 and it ranged from 0.375 (CSSM43) to 0.775 (CSSM61). Average expected Levene’s and Nei’s heterozygosity (Hep) were 0.6...

objective(s): iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. however, to date there is no reliable information on the application of the markers in the iranian pop...

Population genetic structure of stellate sturgeon (Acipenser stellatus) in 197 adult specimens from four fishery regions along the Iranian coastline of the southern Caspian Sea was investigated using microsatellite markers. Out of 15 microsatellite primers, 11 loci were produced, in which 10 of them were polymorphic and 1 was monomorph. Totally, 184 alleles were identified and on average 13.1 a...

The Uruguayan Creole cattle genetic reserve consists of a herd of about 600 animals (bulls, cows and calves) located in an indigenous habitat of 650 hectares. In a previous study, a random sample from this herd showed high heterozygosity and a Hardy-Weinberg equilibrium for markers of major genes related to milk production. To study its genetic diversity we genotyped a sample of bulls (N = 19 o...

The Meliponini, also known as stingless bees, are distributed in tropical and subtropical areas of the world and plays an essential role in pollinating many wild plants and crops These bees can build nests in cavities of trees or walls, underground or in associations with ants or termites; interestingly, these nests are sometimes found in aggregations. In order to assess the genetic diversity a...

Allozyme genetic variability in five natural populations of Cyclobalanopsis championii (Fagaceae) in Taiwan was investigated using 12 loci from 9 enzyme systems. The average values of parameters describing within-population variation, expected heterozygosity (He = 0.151), the percentage of polymorphic loci per individual (P = 50%), the average number of alleles per locus (A = 1.7), effective nu...

Tibetan is a valuable Himalayan sheep breed classified as endangered. Knowledge of the level and distribution of genetic diversity in Tibetan sheep is important for designing conservation strategies for their sustainable survival and to preserve their evolutionary potential. Thus, for the first time, genetic variability in the Tibetan population was accessed with twenty five inter-simple sequen...

The present study was to construct a parentage verification system for Iranian Caspian horse. A total number of 45 Caspian horse samples including 14 foals for parentage verification, 17 stallion and 14 mare for individual identification were genotyped. Genomic DNA was extracted from whole blood and the genotype were analysed by PCR procedure and using 7 microsatellite markers (AHT04, HMS03, HM...

A specific formulation is presented for the correlation between the heterozygosity of a randomly mating parent and its offspring for a diallelic locus, and for the correlation when multiple loci are onsidered. The expected correlation is maximal, approaching r=0.50, when allelic frequencies are highly asymmetric, and it is zero when the allelic frequencies are equal to 0.50. Multilocus allozyme...

Common kilka Clupeonella cultriventris (Nordmann, 1840) is a brackish water and small pelagic fish species and is one of the most abundant fishes that live gregariously in the Caspian Sea. A total of 60 specimens of adult common kilka were sampled from two seasons. Fifteen pairs of microsatellites previously developed for A.sapidissima, C. pallasi, C.harengus, and S. pilchardus were tested for ...
