Note. PTB means Putian Black duck (N = 112), PTW means Putian White duck (N = 107), LC means Liancheng White duck (N = 107), and LS means Longsheng Jade-green duck (N = 106). PIC means polymorphism information content. PIC < 0.25 indicates a low level of polymorphism, 0.25 < PIC < 0.5 indicates a medium level of polymorphism, and PIC > 0.5 indicates a high level of polymorphism.
