Allozyme analysis was used to assess genetic variability in tephritid fruit fly Bactrocera diversa and B. zonata. In our experimental conditions, allozyme analysis at twelve enzyme loci scores twenty one putative alleles. The amount of mean observed heterozygosity (HO) was 0.22 and 0.28 and amount of mean expected heterozygosity (HE) was 0.28 and 0.37, in B. diversa and B. zonata, respectively....

in the present study, genotyping of six short tandem repeat (str) loci including csf1po, d16s539, f13a01, f13b, lpl and hprtb was performed on genomic dna from 127 unrelated individuals from the iranian province of isfahan. the results indicated that the allele and genotype distributions were in accordance with hardy-weinberg expectations. the observed heterozygosity (ho), expected heterozygosi...

The pituitary-specific transcription factor (PIT1) gene is responsible for pituitary development and hormone secreting gene expression in mammals. PIT-1 is studied as a candidate genetic marker for growth, carcass and also for milk yield traits. In dairy farm animals, the principal goal of the selection is the improvement of milk yield and composition. The genes of milk proteins and hormones ar...

Calpastatin (CAST) is a specific inhibiter of Calpains, playing a role in meat tenderization and myogenesis. In the present study the polymorphism of the CAST gene ofKhalkhali goat in Azerbaijan province in Iran was investigated by polymerase chain reaction and restriction fragment length polymorphism technique (PCR-RFLP). Genomic DNA was extracted from whole blood samples collected from 200 Kh...

Multilocus enzyme electrophoresis data from 14 orthologous loci (25 alleles) were used to infer the genetic variation between the two Tephritidae species, Bactrocera (Dacus) cucurbitae and B. (D.) dorsalis, which are common pests of vegetables and fruits in India. Out of fourteen loci analyzed, seven loci were polymorphic in B. cucurbitae and nine loci were polymorphic in B. dorsalis. The amoun...

Under the assumptions of a subdivided population and the presence of dominance for fitness, the expected sum of heterozygosity in the total population during the lifetime of mutant was investigated. It was shown analytically and by computer simulations that in the island model the effect of dominance on the expected sum of heterozygosity decreases as the migration rate decreases and is lost alm...

The genetic diversity and differentiation of three Chinese Bruguiera gymnorrhiza populations was examined in this study: Expected heterozygosity at species and population levels was 0.293 and 0.268, observed heterozygosity was 0.2745 and 0.2705, respectively. The genetic diversity between populations was 0.0830, which showed that among total heterozygosity, 8.3% came from inter-population. Gene...

to clarify the genetic relationships among the lidia breed lineages and two main portuguese lidia bovine populations, casta portuguesa and brava dos açores, 24 autosomal microsatellites were analyzed in 120 samples. brava dos açores showed the highest observed and expected heterozygosity (0.73 and 0.70, respectively) while casta portuguesa showed the lowest observed and expected heterozygosity ...
