Genome-Wide Association Study of Body Weight Traits in Chinese Fine-Wool Sheep
Body weight is an important economic trait for sheep and it is vital for their successful production and breeding. Therefore, identifying the genomic regions and biological pathways that contribute to understanding variability in body weight traits is significant for selection purposes. In this stud...
