Histogram distribution of a given group of S. viminalis accessions by allele-specific read coverage for two selected markers. Each bar signifies a read depth class 10 reads wide. The left column of subplots (a, c, e) shows the distribution of accessions categorized by called genotype across the read depth of a normally behaving marker whereas the right column (b, d) shows the distribution of sex-specific accessions across the read depth of sex associated marker 1)
