In order to investigation of chromosomal variation in various populations of Aegilops cylindrica from northwest of Iran, the karyotype of each populations was prepared using aceto-iron-hematoxilin staining and different chromosomal characteristics were measured. The results showed that the karyotype of these populations consisted of seven pairs of metacentric, three pairs of submetacentric and ...
the aim followed in this study was to use the multi and single trait analyses for a prediction of genomic and traditional breeding values and to make a comparison of the accuracies of these methods. a base population of 100 animals (50 males and 50 females) was randomly mated for 50 generations to create linkage disequilibrium among loci. the simulated genome size was 10 morgan, equally divided...
Preparation of chromosome spreads and karyotype analysis in Blicca bjoerkna transcaucasica were carried out using 0.01% solution of colchicines and Phytohaemagglutinin (PHA) (20 µg g-1 body weight). The gill and kidney tissues were collected and let to stand in a hypotonic solution of 0.075 M KCl and then treated with a fixative (Carnoy's solution) in three steps. The chromosomes spreads were...

writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
abstract the current study set out to address the issue as to whether the implementation of portfolio assessment would give rise to iranian pre-intermediate efl learner autonomy. participants comprised 60 female in pre-intermediate level within the age range of 16-28.they were selected from among 90 language learners based on their scores on language proficiency test -key english test. then, t...
in this study reference as one of the five cohesive devices in the achievement of textuality in english and persian narrative/descripitive written texts is focused on and analysed . to do so , the theoretical framework elaborated by halliday and hasan (1976) and its version adapted by the writer to match the sub-types of reference in farsi are applied to the analysis of reference in english and...
the polygene chromosomal pattern together with the somatic and meiotic chromosomes of the autogenous tehran strain of culex pipiens molestus is described. the first and third chromosomes are metacentric, the second one is slightly submetacentric. each chromosome has well-defined, large puffed characteristic centromeres. randomly distributed asynaptic regions on the polytens chromosomes are ind...
human chromosomes in amnion cells and lymphocytes with normal karyotype and in lymphocytes with pathological karyotype (2n=47, +21) were compared as to their position in the metaphase. none of the collectives showed sex differences. measurement of the radial distances revealed more peripheral position of the majority of large chromosomes. the satellite-carrying chromosomes of the d group always...
the chromosome number and type as well as karyotype in vimba vimba persa were studied. a total of 200 larvae and 10 fingerlings of this species with an average weight of 30.2g obtained from shahid ansari fish hatchery. to arrest mitosis in metaphase, larvae under study were placed in a 0.05% solution of colchicine for a period of 6h while the fingerlings were given an intramuscular injection of...
