Inferring Phylogenetic Networks with Maximum Pseudolikelihood under Incomplete Lineage Sorting

Accuracy of SNaQ to recover the major tree in the species network, from sequence alignments.

The major tree is obtained by suppressing all minor hybrid edges (γ < 0.5) to capture the major vertical inheritance pattern. Accuracy is measured as half the Robinson-Foulds distance between the true and estimated tree, i.e. the number of incorrect edges in the estimated tree. A lot fewer genes are needed to accurately estimate the major vertical pattern, compared to the horizontal pattern.
