Gene trees and species trees can be incongruent for many reasons. (A) Genes can have unequal rates of evolution. (B) Gene loss and gene duplication are common. (C) Gene flow can occur between.. correcting gene trees (PANTHER [20]), or by avoiding reconciliation by integrating the orthology identification procedure with the gene tree construction procedure [21]. However, even when the gene tree is statistically well-supported by the data, the reconciliation approach can lead to an erroneous duplication and loss history for the

Fig. II shows an example in which the gene tree and species tree do not match. There are three species (H, C and G); although H and C share the most recent ancestry, the history of the genes is different and the genes of C and G share the more recent ancestor (X). This occurred because the lineages from H and C remained separate for the period T3.. A species tree is a phylogenetic tree that represents the evolutionary pathways of a group of species. A gene tree is a phylogenetic tree constructed from a single gene from each of the species under study. eLS.
