Relationships between matrix size and resolution in current study and meta-analysis of published studies. A) Parsimony resolution of jackknifed partitions (black circle) of full alignment of current study. Labelled data points (triangle) represent resolution of the following: a - Wang et al. , b - Gernandt et al. , c - Eckert and Hall , d - ycf2, e - ycf1, f - combined ycf1 and ycf2, g - exon nucleotides, h - complete alignment. B) Relationship between matrix length and phylogenetic resolution in published studies (N = 99). C) Relationship between number of taxa and phylogenetic resolution in published studies (N = 99). Regression lines are shown in red; 95% confidence intervals shown in blue. X-axes of A, B and C and Y-axes of B and C are in log scale.
