Reconciliation feasibility in the presence of gene duplication, loss, and coalescence with multiple individuals per species.

ABSTRACT:

Background

In phylogenetics, we often seek to reconcile gene trees with species trees within the framework of an evolutionary model. While the most popular models for eukaryotic species allow for only gene duplication and gene loss or only multispecies coalescence, recent work has combined these phenomena through a reconciliation structure, the labeled coalescent tree (LCT), that simultaneously describes the duplication-loss and coalescent history of a gene family. However, the LCT makes the simplifying assumption that only one individual is sampled per species whereas, with advances in gene sequencing, we now have access to multiple samples per species.

Results

We demonstrate that with these additional samples, there exist gene tree topologies that are impossible to reconci
