Genetic relationships between mitochondrial DNA from Dingoes, Domestic Dogs, and Wolves
Genetic relationships between mtDNA control region sequences (582 bp) from dingoes, domestic dogs, and wolves.
(A) Phylogenetic tree showing all dog, wolf, and dingo mtDNA types. Unlabeled leaves denote mtDNA types from domestic dogs, yellow circles denote types unique to dingoes, red circles denote types found in both dingo and dog, and squares denote wolf mtDNA types. The tree is rooted to coyote sequences. Dog clades A–F are indicated with letters.
(B) Minimum-spanning network of the main dog clade (clade A). Sequence types (circles) and empty nodes (solid dots) are separated by one mutational step (substitutions; indels are not shown). The mtDNA type indicated by bold lines has four shortest links (with a length of three mutational steps) to other mtDNA types, but two of these are not shown to simplify the figure.
- Yellow - unique dingo mtDNA type.
- Red - type found in both dingo and dog.
- Blue - type found in dogs in Indonesia, the Philippines, or Malaysia.
- Green - unique New Guinea type.
- Squares denote wolves.
- Areas of red and yellow circles are proportional to frequencies among dingoes, but the area of A29 is reduced by 50%.
