Widespread discordance of gene trees with species tree in drosophila: evidence for incomplete lineage sorting

Although the genome - wide species phylogeny supported a single topology (fig. 1), rarely will the entire genome reflect a single topology, as incomplete lineage sorting and gene flow can distort the underlying species tree (Degnan and Rosenberg 2009).

To examine the degree of admixture and incomplete lineage sorting, we looked at each gene topology and compared it to the species tree.

Approximately, unbiased (AU) tests (Shimodaira 2002) were conducted for each gene to test for significant support of either the species tree (major topology) or the two minor tree topologies.
