Change of heterozygosity in multiple regions of TC7 chromosome 5. A Genomic distribution of distinct SNVs between TC7 individual samples and the PC group. Roman numerals indicate SNV-rich regions. B Composition of alleles at SNV sites in the four indicated TC7 SNV-rich regions. SNV sites were classified as homozygous (homo) for reference (Ref) or alterative (Alt) alleles or heterozygous (hetero) for two alleles. C Alleles at selected SNV sites in the four TC7 SNV-rich regions. For each diallelic site, reference or alternative alleles in a homozygous or heterozygous state are shown as a color composite. Asterisks mark the sites falling within SNP clusters. D Distribution of the variant allele ratio (VAR) at the heterozygous sites in the four TC7 SNV-rich regions. The VAR was calculated as the read count of the variant allele divided by the total read count at each heterozygous site. The numbers of heterozygous sites analyzed in each plot are indicated in parentheses. E Numbers of genes in the four TC7 SNV-rich regions
