The present work estimated the genetic variability and relatedness index of the fifth stock of Pacific white shrimp, Litopenaeus vannamei, imported into Cuba for farming purposes from the US Shrimp Improvement System (SIS). Genetic variability was estimated by genotyping 33 samples for four microsatellite loci: M1, Pvan 1815, Pvan 0040 and Pvan 1758. This stock had average expected and observed...
Understanding the genetic diversity of different Pakistani mango varieties is important for germplasm management and varietal characterization. Microsatellites are efficient and highly polymorphic markers for comparative genome mapping, and were used in the present study to determine the genetic relatedness and variability among 15 indigenous mango cultivars (Mangifera indica L.). Overall, 181 ...
Prunus rootstocks play an important role in modern horticulture and commercial orchards owing to their responsibility for a wide range of characters from compatibility with cultivars to adaptation to biotic and abiotic stresses. In this study, Thirty Prunus rootstock samples were tested by 25 microsatellite markers in order to identify the genetic identity and relationships among them.17 SSR ma...
Kin selected benefits of cooperation result in pronounced kin discrimination and nepotism in many social species and favour the evolution of sociality. However, low variability in relatedness among group members, infrequent competitive interactions with non-relatives, and direct benefits of cooperation may relax selection for nepotism. We tested this prediction in a permanently social spider, S...
The broadnose sevengill shark, Notorynchus cepedianus, a common coastal species in the eastern North Pacific, was sampled during routine capture and tagging operations conducted from 2005-2012. One hundred and thirty three biopsy samples were taken during these research operations in Willapa Bay, Washington and in San Francisco Bay, California. Genotypic data from seven polymorphic microsatelli...
بررسی تنوع ژنتیکی ژنوتیپهای بومی پیاز ایرانی در مقایسه با انواع خارجی چکیده: برنامه های اصلاحی گیاهان بر اساس تنوع و انتخاب صفات برتر کمی و کیفی صورت می گیرد. لذا، ارزیابی تنوع ژنتیکی، اولین مرحله در برنامه های اصلاحی است. در این راستا، استفاده از روش های جدید مطالعهی تنوع ژنتیکی ضروری به نظر می رسد. در این بررسی تعیین تنوع ژنتیکی سیزده ژنوتیپ پیاز ایرانی در مقایسه با دو ژنوتیپ خارجی با است...
This study is the first attempt to establish an SNP database for the purpose of estimating the genetic diversity and relatedness of Palestinian lentil genotypes. A total of 14 lentil accessions (11 local, two supplied by ICARDA, and one introduced from Italy) were investigated. By sequencing two genes, lectin and lipid transfer protein 5 (LTP5), four SNPs were detected (three in the first and o...
Small intestinal neuroendocrine tumors (SI-NETs) are rare tumors arising from the enterochromaffin cells of the gut. Having a first-degree relative with a SI-NET has been shown to confer a substantial risk arising from shared environment and genetics. Heritable risk was examined using a computerized genealogy linked to historical statewide cancer data. A population-based analysis of the observe...
