Comparing reference bias in published ancient genomes that FASTQ file available aligned with different reference genomes and PMD-effects reduced with different approaches. The plot shows the proportion of alternative alleles after randomly selecting one allele from heterozygote sites 100 times. We used reads with MAPQ > 30 for genotyping. To compare results with MAPQ > 25, see Additional file 1: Fig. S29. (see also Additional file 1: Figs. S30-31)
