Linkage disequilibrium (LD) is bases of genomic selection, genomic marker imputation, marker assisted selection (MAS), quantitative trait loci (QTL) mapping, parentage testing and whole genome association studies. The Particular alleles at closed loci have a tendency to be co-inherited. In linked loci this pattern leads to association between alleles in population which is known as LD. Two metr...

Calpastatin is an endogenous inhibitor of calpain (calcium-dependent cysteine protease). Calpastatin activityis highly related to the rate of protein turnover and rate of meat tenderization. In order to characterize thestructure of calpastatin in Iranian Afshari breed of sheep, intron 6 and partial exon 7 of the L domain wereamplified and sequenced. A fragment of approximately...

Markers are any trait of an organism that can be identified with confidence and relative ease, followed in a mapping population or they defined as heritable entities associated the economically important under control polygenes. Molecular markers have diverse applications fruit crop improvement, particularly areas genetic diversity varietal identification studies, disease diagnostics, hybrid de...

Marker-assisted selection holds promise because genetic markers provide completely heritable traits than can be measured at any age in either sex and that are potentially correlated with traits of economic value. Theoretical and simulation studies show that the advantage of using marker-assisted selection can be substantial, particularly when marker information is used, because normal selection...

Marker assisted backcrossing has been used effectively to transfer the submergence tolerance gene SUB1 into popular rice varieties, but the approach can be costly. The selection strategy comprising foreground marker and phenotypic selection was investigated as an alternative. The non-significant correlation coefficients between ranking of phenotypic selection and ranking of background marker se...

Marker-assisted background selection is a powerful molecular tool that can enhance breeding efficiency through the analysis of large number markers representing entire genomic for precise selection. In present study, transcriptomes 38 cucumber inbred lines with diverse traits were sequenced single nucleotide polymorphism (SNP) mining practical application to commercial breeding. A total 62,378 ...
