Saturation (genetic)

Genetic saturation is the result of multiple substitutions at the same site in a sequence, or identical substitutions in different sequence, such that the apparent sequence divergence rate is lower than the actual divergence that has occurred. In phylogenetics, saturation effects result in long branch attraction, where the most distant lineages have misleadingly short branch lengths. It also decreases phylogenetic information contained in the sequences.
