Trree Mol Biol. Resumen Background: What is the phylogenetic tree represent, or Horizontal, Gene Transfers are a type of asymmetric evolutionary events where genetic linear equations 8th grade worksheets is transferred from one species to another.

In this paper we consider LGT networks, a general model of phylogenetic networks with lateral gene transfers which consist, roughly, of a principal rooted tree with its leaves labelled on a set of taxa, and a set of extra secondary arcs between nodes in this tree representing lateral gene transfers. An LGT network gives rise in a natural way to a principal phylogenetic subtree and a set of secondary how to make a line graph in excel with 4 sets of data subtrees, which, roughly, represent, respectively, the main line of evolution of most genes and the secondary lines of evolution through lateral gene transfers.

Results: We introduce a set of simple conditions on an LGT network that guarantee that its principal and secondary phylogenetic subtrees are pairwise different and that these subtrees determine, up to isomorphism, the LGT network. We then give an phylogejetic that, given a set of pairwise different phylogenetic trees T-0, T-1, Palabras clave Phylogenetic network Lateral gene transfer Horizontal gene transfer Phylogenetic tree.
