Table 3.
Cline analysis results for yellow bar phenotype, AFLP genotype and mitochondrial clade. For cline midpoint and cline width, the 95% confidence intervals are given in parentheses. The best fitting model is indicated in the “Model” column with three asterisks (***). Note that y1 and y2 values for hindwing yellow bar width are the 1-scaled values (see Methods).
