Association of novel polymorphisms in the bovine myocyte enhancer factor 2D (MEF2D) gene with carcass traits of Polish Holstein-Friesian cattle
MEF2D gene gene polymorphism combined genotype meat contents bulls
2015/6/24
In the present study the polymorphism of the myocyte enhancer factor 2D (MEF2D) gene was analyzed as a genetic marker candidate for carcass traits in Polish Holstein-Friesian cattle. Four novel single...
Testing different single nucleotide polymorphism selection strategies for prediction of genomic breeding values in dairy cattle based on low density panels
3K chip genomic selection prediction single nucleotide polymorphism
2015/6/24
In human and animal genetics dense single nucleotide polymorphism (SNP) panels are widely used to describe genetic variation. In particular genomic selection in dairy cattle has become a routinely app...
