honeybee is a pollinator that has prominent role in agriculture products and nourishment for human. so, the most number of studies like genetic improvement were done on honeybee. recent advances in knowledge of molecular genetics of bee emphasize the potential for using genetic markers to select favored traits. this research was done to determine polymorphism of loci of first foraging age (aff)...

recent years, evidence has accumulated which indicates that genetic re'2mbination occurs not only between different loci but also between alleles within one locus (PONTECORVO 1958). A precise genetic analysis of allelic relationships within one locus is certainly an essential approach to understanding genes, since studies of allelism can help to elucidate both the structure and function of a pa...

in this study, genetic diversity of 20 wheat genotypes was evaluated using 126 simple sequence repeats (ssr) alleles, covering all three wheat genomes. a total of 1557 allelic variants were detected for 126 ssr loci. the number of alleles per locus ranged from 4 to 19 and the allelic polymorphism information content (pic) varied from 0.66 (xgwm429) to 0.94 (xgwm212 and xgwm515). the high­est po...

Four Saudi Arabian indigenous sheep populations including Najdi, Hbsi, Arb, and Naemi were genotyped for 16 microsatellite markers recommended by the food and agriculture organization (FAO). This study aims to provide information on the genetic structure of the breeds analyzed and give indications and proposals for the cross breeding program. All loci were polymorphic in all populations and loc...

genome-wide association studies (gwas) have identified genetic variants contributing to the risk of cardiovascular disease (cvd) at the chromosome 9p21 locus. the chromosome 9p21 is an important susceptibility locus for several multifactorial diseases like ischemic stroke, aortic aneurysm, type 2 diabetes mellitus and coronary artery disease (cad). f7 gene because of its role in activating the ...

to assess the genetic relationships between 72 cultivated and 65 wild grapevines in west azerbaijan and in kurdistan, 19 ssr markers were employed. microsatellitic primer pairs amplified, a total of 163 alleles with an average of 8.6 alleles/locus (for cultivars) and 153 alleles with an average of 8.05 alleles/locus (for wild samples). the expected heterozigosity varied from 0.7 in cultivars to...

Correlation of the complementation relationships between the Notch locus alleles fa(g), fa(no), Ax(59d) and nd, with their genetic map order, suggests a tandem repetition within the locus of functionally related sites. This observation is discussed in relation to two hypotheses: (1) that the Notch locus contains a tandem repeat of genetic material; and (2) that the tertiary structure of the Not...
