Fig. 4From: Quantifying and reducing spurious alignments for the analysis of ultra-short ancient DNA sequencesPercentage of derived allele sharing with the Denisovan and Neandertal lineages. The circles and diamonds correspond to the L10% and 35-bp length cutoffs, respectively. Bars indicate 90% binomial confidence intervals. The difference between Neandertal and Denisovan sharing is statistically significant in all comparisons, except for the SH Molar with the 35-bp cutoff highlighted in the gray area (Fisher exact test p value = 0.09)Back to article page
