background: infection with trichostrongylus spp. is common among human and herbivorous in most parts of iran, especially in southern and northern ar-eas. the aim of present study was to identify trichostrongylus spp. among hu-man population using excreted egg specimens, by the molecular method, in mazandaran province, northern iran. methods: overall, 33 positive fecal specimens were randomly sa...

having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. in present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and rapd markers. significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...

it is important to identify the genetic diversity and phylogenic relationships for achieving desirable citrus cultivars. in present investigation rapd markers were used to determine genetic diversity among 29 citrus genotypes. from 19 used primers, 248 polymorphic bands were amplified. primers opa-07 and opa-05 (with 19 and 8 amplified bands), produced maximum and minimum polymorphic bands, res...

The occurrence of polymorphism in a series of 87 different loci coding for enzyme structure in human populations has been related to the size and the number of subunits in the corresponding enzymes. Polymorphic and nonpolymorphic enzymes did not differ on average in subunit size. However, multimeric enzymes showed a significantly lower incidence of polymorphism than didmonomeric enzymes. A part...
