Experimental design and variant statistics. a Geographical origins of the 9 chicken breeds used in this study. The map was created by the Adobe Illustrator (AI) 2019 software (http://adobe.e-bridge.com.cn/shop/index.html). b Summary of genomic resequencing data from 5 Xichuan black-bone chickens. The figure shows the distribution of SNPs, indels, and SVs. Chromosomes are represented in different colors in the outermost circle. The remaining circles, in order from the outside to the inside, are as follows: genes, SNPs, indels, and SVs. c Distribution of SNPs based on context. Different colors represent SNPs within various functional regions. One circle represents 1% of total SNPs. d Heat map depicting genetic relationships based on SNP data obtained for the 29 chickens that represented the 9 breeds. Colors represent pairwise genetic distances
