Mitochondrial genome structural changes coincide with SNP-based phylogeny. Structural changes arising by nonhomologous end-joining (NHEJ), deletions caused by recombination at repeats (REC) and small deletions, perhaps arising by replication slippage (DEL), were categorized according to ecotypes, allowing assessment of the relationship of SNP-based phylogeny to changes arising by genomic rearrangement. Putative sites in the tree where some of the changes may have occurred are indicated. The tree shown is unrooted.
