Distribution of heterozygosity along a genomic segment of T. c. marinkellei . Distribution of heterozygosity and sequence coverage along scaffold 143 of T. c. marinkellei B7. Heterozygosity was counted in non-overlapping sliding windows of 1000 bp (red line). Coverage is shown as the log10-scaled average coverage of the 1000 bp window (turquoise line). The x-axis shows the start position of the window along the sequence and the y-axis shows the number of heterozygous nucleotide positions per window or log10-scaled average coverage of the window.
