Extended Data Fig. 7: Frequency of nucleotide substitutions at the beginning and the ends of mtDNA alignments for the Bacho Kiro Cave specimens.
From: Initial Upper Palaeolithic Homo sapiens from Bacho Kiro Cave, Bulgaria
Only fragments of at least 35 base pairs in length that mapped to the revised Cambridge Reference Sequence with a mapping quality of at least 25 were used for this analysis. Solid lines in red depict all fragments and dashed lines depict the fragments that have a C-to-T substitution at the opposing end (‘conditional’ C-to-T substitutions). All other types of substitution are marked in grey.
