Spearman's rank correlation coefficients for correlations of D statistics of 2000 potentially homologous genes in pair-wise comparisons of A. formosa and A. thaliana (stage 12) floral whorls and traditional A, B, and C domains. Highest A. formosa correlation coefficients are given in bold whereas highest A. thaliana coefficients are italicized. Statistically significant coefficients are marked with an asterisk.
