Note: The mtDNAs of TF02, TF03, TF04, TF10, TF13, and TF16 were identical, and that of TF11 and TF14 were same. Therefore information for TF04 represents that of the other five; information of TF11 represents that of TF14 in this table. Superscript 1 represents the big insertion fragment in the intergenic region; superscript 2 represents the intergenic region except for big insertion fragment. Dash means data unavailable. Mutation rates were represented by the number of single nucleotide polymorphism per one kb sequences
