WebNov 1, 2011 · In addition, the Bayesian hypothesis test is able to identify unlikely gene families based on Bayesian posterior p-values. As a powerful statistical technique, the … WebMore specifically, the characters of a gene tree are base the of a gene's nucleotide sequence. When a mutation event occurs, a new allele arises in the gene tree. This divergence is represented by a branch, and each of the various alleles in the sample group are represented by a tip with one common ancestral allele at the root.
