Abstract Yellowfin seabream (Acanthopagrus latus), an important economical species and popular market fish found in the coastal water of Persian Gulf. In this study, eight microsatellite loci were used, population structure and genetic diversity of this species was studied in six fishing area in the Persian Gulf. Alleles observed in different stations were between 7 to 12 with an average of 9...
The poor information available on variation of Ascochyta blight fungus is the most important factor limiting chickpea breeding programs for resistance to blight disease. In this study, efforts were made to detect genetic variation of the pathogen in Iran. The RAPD marker was employed to evaluate 26 isolates collected from 16 provinces. Twelve random primers were used to analyze genomic DNA of t...
ارزیابی روابط ژنتیکی بین 36 ژنوتیپ از گونه های کلزا (Brassica sp.) با استفاده از نشانگر مولکولی ISSR
Study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. Since the hybrid canola have more yield than inbred lines, determine the genetic diversity of this have particular importance. In the present study, genetic diversity among 36 genotype of Brassica sp. were determined using inter simple sequence repeat (ISSR) markers...
This study was conducted to estimate the genetic parameters of litter size (LS) in Moghani sheep using threshold model via Bayesian approach. The data originated from the Jafar-Abad Station of Ardabil province, Iran, and included 9698 lactation records of 4977 ewes with lambings from 1995 until 2010. The pedigree file consisted of data on animals born from 1987 to 2010. The significance of fixe...
Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...
Little information is available regarding genetic variation in wild wheat relatives from Iran. In this study, genetic diversity of 36 populations of wild einkorn wheat, Triticum boeoticum, was studied using amplified fragment length polymorphism (AFLP) primer combinations. Seventeen AFLP primer combinations led to amplify 979 scorable fragments ranging from 50 to 500 bp and of these, 429 (44%) ...

The science of medical genetics is progressing rapidly. The practical importance of this progress should be considered by medical doctors. Both genetic and environmental factors are involved in the abnormail phenotypes considered diseases. The relative significance of the two factors varies from disease to disease. All diseases can be viewed as falling on a spectrum in this regard. Hereditary...
The effect of ordinary and restricted selection indices on body weight at different ages changes in birth weight of Iranian Moghani sheep was studied. Traits in the aggregate genotype were birth weight (BW), body weights at 3 (BW3) and 12 months of age (BW12). Two ordinary selection indices (I1 and I2) and two restricted selection indices (R1 and R2) were constructed. BW and BW3 were included i...
