Sample distribution. Solid circles are samples sequenced in this study. Open circles indicate sequences from Zhang et al. (2014). Triangles and boxes indicate sequences from Wang et al. (2013) and Freedman et al. (2014), respectively. Species memberships are indicated by color: gray wolf (red), domestic dog (blue), coyote (green), and golden jackal (yellow). The reference dog genome is from a boxer.
