摘要
Orthology detection is an important problem in comparative and 演化ary genomics and, consequently, a variety of orthology detection methods have been devised in recent years. Although many of these methods are dependent on generating gene and/or 物種 trees, it has been shown that orthology can be estimated at acceptable levels of accuracy without having to infer gene trees and/or reconciling gene trees with 物種 trees. Thus, it is of interest to understand how much 資訊 about the gene tree, the 物種 tree, and their reconciliation is already contained in the orthology relation on the underlying set of genes. Here we shall show that a result by Bocker and Dress concerning symbolic ultrametrics, and subsequent algorithmic results by Semple and Steel for processing these structures can throw a considera
