Figure 1

Illustration of parsimony inference from a gene/presence pattern and a reference tree topology. (a,b) Results of parsimonious inferences for the same gene family, with different criteria used to define presence/absence patterns. In (a) genes are divided into only two categories, present and absent, while in (b) the absent genes are further classified into gene remnants and genuinely absent.
