Progress on the Effect of X Chromosome Genome on Production Traits in Dairy Cattle
The search for quantitative trait loci(QTL)affecting traits of interest in mammals is usually limited to autosomes,and X chromosome variation has not yet been included in genomic prediction equations used to estimate animal breeding values.In contrast,the X chromosome,as the second largest chromosome in cattle,bears important biological significance,and as genomic work has intensified,functional studies of genetic variation on the X chromosome have increased,and the inclusion of X chromosome genomic marker information in analyses can improve the prediction of genomic breeding values.In this study,we reviewed the progress of research on association analysis of genes on the X chromosome with traits such as milk production,reproduction,health,body size and productive longevity in dairy cows,with a view to providing assistance in research to improve the production performance of dairy cows.
