Principal component analysis of genomic variables and Neu. a PCA biplot from raw data. b PCA biplot from phylogenetically independent contrasts. The horizontal scale denoted principal component 1 (PC1) and the vertical scale denoted principal component 2 (PC2) in the biplot. The genomic variables are genome size in Mb (Genome.size), average intron size in bp (Av.intron.size), number of genes (No.of.gene), average introns per gene (Av.intron.per.gene), all marked in red. The effective population size and mutation rate (Neu) also marked in red. The red arrows showed the magnitude and direction of the genomics variables and Neu vectors
