Figure 6

Linear regressions of five reproductive morphological traits against FCA homolog average allele lengths. Five reproductive morphological traits show similar linear correlations with FCA homolog average allele length per Hawaiian mint individual. The x-axis is average allele length, and the y axis represents measurements in millimeters. Dark blue = nutlet size; green = corolla lower lip length, light blue = corolla upper lip length, red = number of flowers per verticillaster, yellow = pedicel length. Regression lines, from top to bottom at the y-intercept,: pedicel length, flowers per verticillaster, corolla upper lip length, corolla lower lip length, nutlet size. See Table 2 for R² and significance values. Note that none of these morphological variables show significant correlation with average allele lengths for the other two loci shown in Figure 5.
