Genome-wide association analysis in  yak
Identifying key markers or genes associated with growth traits in Yak is crucial for breeding. Precisely locating genetic factors related to body conformation and growth can improve breeding efficiency and economic value. In this study, low-coverage sequencing was used to resequencing 536 Yak individuals at different growth stages for four growth trait indices: body weight (BW), body height (BH), body oblique length (BOL), and chest circumference (CC). Genome-wide association studies (GWAS) were conducted to identify candidate genes associated with these four body measurements, thereby laying the foundation for subsequent studies on the biological functions of these genes.
