Clone sequences used to determine ancient muskox mtDNA sequence. MMO1-8 represent the 8 haplotypes already identified in modern muskoxen . The modern samples are also shaded. Samples are indicated by name (following the naming system in ) followed by the PCR repetition number followed by clone number i.e. 1.1 is the first clone sequence from the first PCR amplification. Indels that are in conflict with the published sequences are indicated "*". Base changes that were found only in samples from Taimyr but were not fixed are designated "§". Fixed differences between ancient Taimyr samples, with the exception of OMTai23564, are also indicated "#".
