BACKGROUND AND AIMS Despite the great importance of autopolyploidy in the evolution of angiosperms, relatively little attention has been devoted to autopolyploids in natural polyploid systems. Several hypotheses have been proposed to explain why autopolyploids are so common and successful, for example increased genetic diversity and heterozygosity and the transition towards selfing. However, ca...

 Population genetic structure of Vimba vimba persa was investigated using microsatellite markers from 40 regions along the Iranian coastline of the Southern Caspian Sea (Anzali lagoon and Havigh River in Gilan province, BabolRoud River in Mazandaran province and GorganRoud River in Golestan province). Genomic DNA from 121 specimens was extracted from fin tissue by the Phenol-Chlorophorm method ...

Kiwifruit belonging to the Actinidiaceae family is a perennial, dioecious vine called ‘the king of fruits’ due its considerably nutritious and sweet characteristics. A. chinensis complex, including two main groups, var. deliciosa, major component Actinidia their huge economic value high degree development utilization. Wild resources are widely distributed in China, but under serious threat extr...

The present study aimed at analyzing the genetic variability of indigenous goat breeds (Capra hircus) using the MHC-associated microsatellite markers BF1, BM1818, BM1258, DYMS1, and SMHCC1. The following breeds were included: Chinese Xuhuai, Indian Changthangi and Pashmina, Kenyan Small East African (SEA) and Galla, and Albanian Vendi. To examine genetic variability, the levels of heterozigosit...

Background: Potato has a narrow genetic base which is due to its development, as it takes its genetic root from a few genotypes originated from South America. Objectives: The objective of this study was to assess the genetic relationships among potato (Solanum tuberosum L.) genotypes originated from different geographical regions.Materials and Methods: This study has rendered 25 use...

To empirically determine the effects of sample size on commonly used measures of average genetic diversity, we genotyped 200 song sparrows Melospiza melodia from two populations, one genetically depauperate (n 100) and the other genetically diverse (n 100), using eight microsatellite loci. These genotypes were used to randomly create 10,000 datasets of differing sizes (5 to 50) for each populat...

nuclear markers such as microsatellites have allowed the identification of conservation and management populations of the hawksbill turtles. in present study, eight microsatellite loci were studied. 60 samples of hawksbill turtles. flipper from shidvar and hormuz islands have been surgically removed and preserved in 20% dmso buffer. dna was extracted using dnp kit and amplified by pcr methods. ...

Loss of heterozygosity occurring on various chromosomes has been described in the majority of human tumors. The targets of frequent or consistent subchromosomal deletions are believed to be tumor suppressor genes. We examined 72 esophageal tumors (46 squamous cell carcinomas and 26 adenocarcinomas) for loss of heterozygosity at the p53, Rb, APC, MCC, and DCC loci. Inclusion of these tumor suppr...
