WebFeb 23, 2009 · Phylogenetic reconstruction in the presence of unrecognized paralogs I consider the problem of resolving the relationship between three species/groups by studying many-gene sets of putative one-to-one orthologs, in which some genes have been duplicated in the ancestor of the three species/groups of interest. Web2 days ago · I obtained the phylogenetic trees from vertlife.org. The raw data is composed of 1000 randomly generated Erikson trees condensed into a consensus tree with consensus.edges in phytools where non-negative least squares edge lengths were computed using the mean patristic distance matrix. This tree is not rooted.
