a Neighbour-joining Network of the True Geese using the ordinary least squares method (with default settings) in SplitsTree version 4.1.4.2 [15], based on genetic distances. b The comparison of degree distributions indicates that the Anser-network is more complex compared to the Branta-network as it contains relatively more nodes with four and five edges.
