Galled tree
WebDec 1, 2024 · Galled trees are studied as a recombination model in population genetics. This class of phylogenetic networks is generalized into tree-child and galled network classes by relaxing a structural condition imposed on galled trees. We provide a solution to an open problem that is how to count and enumerate tree-child networks with fixed … WebHowever, even haplotyping via galled-tree networks appears hard, as the efficient algorithms exist only for very special cases: the galled-tree network has either a single gall or only small galls with two mutations each. Building on our previous results, we show that, in general, haplotyping via galled-tree networks is NP-complete, and it ...

WebMay 31, 2024 · Galled trees have the property that, when we remove the edge orientations (i.e., make them undirected), any biconnected component contains at most 1 hybrid node . There are two well-known generalizations on galled trees. One is level-k networks allowing at most k hybrid nodes in each biconnected component . Thus, galled trees are …
