—Maximum-likelihood estimate of ancestral state reconstruction of chromosome number based on a model of linear rate dependency in ChromEvol (i.e., chromosome number changes depend on the current chromosome number), allowing both ascending and descending dysploid changes (i + 1, i − 1) and WGD (2i). Colors correspond to 2n chromosome numbers, and numbers in brackets indicate the ML estimate of chromosome number for that node. Asterisks refer to the posterior probability for the highest-likelihood reconstruction of chromosome number. Black dots correspond to four of the five palms subfamilies sampled.
