  1. Mean geneticdistance (MGD), net relatedness index (NRI), mean nearest phylogenetic gene index (MNGD) and nearest gene index (NGI) were estimated for each species. 10,000 generations of simulations of random sampling of the phylogenetic tree of each species were performed and P-values were determined by percentages of random samples smaller or larger than observations. MGD and MNGD values for the null model are averages of 10,000 generations of simulations.
