Phylogenetic statistics for loci that BLAST to one of three expressed sequence databases (‘EST’) relative to an equal-sized subsample of loci that do not (‘non-EST’) as well as the full m10wRE dataset (‘Full’).

Statistics were calculated for the full m10wRE dataset, the dataset composed only of the 4,715 loci that blasted to at least one of three expressed sequence databases with E-value P-values approximate the type-I error rate under the null hypothesis that the ‘EST’ loci are drawn from the ‘non-EST’ pool of loci. P-values are calculated as two times the percent of random subsamples that are more extreme than the statistics observed on the ‘EST’ tree.
