Fig. 1From: From pairs of most similar sequences to phylogenetic best matchesLineage-specific rate variation between paralogs. The gene tree, with branch length indicating an additive evolutionary distances, pre-dates the speciation (\(\bullet\)) of the red and blue species. We have \({{\,\mathrm{lca}\,}}(x,y)\prec {{\,\mathrm{lca}\,}}(x,y')\) but \(d(x,y')<d(x,y)\)Back to article page
