Encoding level-3 semi-directed phylogenetic networks by quarnets and quinnets

Niels Holtgrefe, Katharina T. Huber, Leo van Iersel +1

Phylogenetic networks generalize phylogenetic trees as models of evolutionary history, allowing lineages to merge as well as to diverge. For many types of genetic data the root pos…

On Tree-Network Distinguishability and Full Identifiability of Phylogenetic Networks

Jari Brits, Niels Holtgrefe, Leo van Iersel +1

Phylogenetic networks generalize phylogenetic trees to evolutionary histories that include reticulate events such as recombination, horizontal gene transfer, and hybridization. Und…

Bounds on the sequence length sufficient to reconstruct binary level- phylogenetic networks under the CFN model

Martin Frohn, Niels Holtgrefe, Leo van Iersel +2

Phylogenetic trees and networks are graphs used to model evolutionary relationships, with trees representing strictly branching histories and networks allowing for events in which…

Characterizing semi-directed phylogenetic networks and their multi-rootable variants

Niels Holtgrefe, Katharina T. Huber, Leo van Iersel +2

In evolutionary biology, phylogenetic networks are graphs that provide a flexible framework for representing complex evolutionary histories that involve reticulate evolutionary eve…

Distinguishing Phylogenetic Level-2 Networks with Quartets and Inter-Taxon Quartet Distances

Niels Holtgrefe, Elizabeth S. Allman, Hector Baños +4

The inference of phylogenetic networks, which model complex evolutionary processes including hybridization and gene flow, remains a central challenge in evolutionary biology. Until…

Reconstructing semi-directed level-1 networks using few quarnets

Martin Frohn, Niels Holtgrefe, Leo van Iersel +2

Semi-directed networks are partially directed graphs that model evolution where the directed edges represent reticulate evolutionary events. We present an algorithm that reconstruc…
