Physical location ranges of recombination interval 1 (a) and interval 2 (b) (The analysis used all SNPs in the LD block region). Red and blue represent the same or opposite alleles in the Wuzhishan reference genome, respectively. (a) Three types of recombination interval 1 (Interval 1-1, Interval 1-2, Interval 1-3) are identified in the domestic pigs of North China. The maximum range of recombination interval 1 is 46,219,219-46,419,569 bp. (b) Three types of recombination interval 2 (Interval 2-1, Interval 2-2, Interval 2-3) are identified in the domestic pigs of North China. The maximum range of recombination interval 2 is 56,819,762-57,752,631 bp.
