The relationship between \( {d}_2^{\ast } \) dissimilarity values and great-circle distances among the tree samples based on sequence quantity of 50, 100 and 300 Mbp. The \( {d}_2^{\ast } \) dissimilarity values are significantly positively associated with the great-circle distances and both the Pearson and Spearman correlation coefficients increased with sequence quantity. However, the \( {d}_2^{\ast } \) dissimilarity is not a strong predictor of great-circle distance
