Introgressed regions between the Guangxi and Southeast/South Asian populations. a Genome-wide distribution of fd values calculated for 100-kb sliding windows with 20-kb steps across the genome to locate the introgressed genomic regions between the Guangxi and Southeast/South Asian populations. Each dot represents a 100-kb window and the dashed line indicates the genomic regions with the strongest introgression signal. b Mean pairwise sequence divergence (d_xy) of the genomic region with the strongest introgression signal on chromosome 1 between the Guangxi and either the Southeast/South Asian or the Chinese domestic populations. c Population differentiation (F_ST) around the genomic region with the strongest introgression signal on chromosome 1 between the Guangxi and either the Southeast/South Asian or the Chinese domestic populations. d Proportion of the Southeast/South Asian ancestral component in the Guangxi population around the genomic region with the strongest introgression signal on chromosome 1 using Chromopainter. e Three genes (PNPLA8, THAP5, and DNAJB9) in the genomic region with the strongest introgression signal (chr1: 172,940,001–173,820,000). The blue bars represent the percentage of individuals with mutations in exons
