Each combination of core-functional category and the different cores proportions are shown. Each cell shows the percentage of cases in which the reference tree topology was rejected at the 0.05 significance level. NA = No data available for this category. Asterisks indicate classes for which only 1 or 2 genes could be used in the analysis.
