has output has topic Gene report Phylogenetic inference Gene tree construction Construct a "gene tree" which represents the evolutionary history of the genes included in the study. This can be used to predict families of genes and gene function based on their position in a phylogenetic tree. beta12orEarlier Gene trees can provide evidence for gene duplication events, as well as speciation events. Where sequences from different homologs are included in a gene tree, subsequent clustering of the orthologs can demonstrate evolutionary history of the orthologs.
