Abstract excerpt

Total rib number (TRN) and total teat number (TTN) are key anatomical and economic traits in pigs, linked to carcass yield and reproductive performance, respectively, and are genetically correlated. However, the shared genetic basis underlying these traits remains incompletely understood. This study aimed to dissect the genetic architecture of TRN and TTN and to identify pleiotropic genes affecting both traits....
