Figure 4

Genetic clines of two example loci (locus 8 and locus 26) that significantly deviate from neutral expectations. Locus names and P-values for the test of departure from neutrality are given in each plot. Solid lines represent the estimated clines while the grey regions indicate the 95% confidence intervals for multinomial logistic regression fits to simulated data under the assumption of neutral introgression. Circles indicate the raw marker data (AFLP ′band absent′ on top line and AFLP ′band present′ along the bottom), with counts of each on the right vertical axis.
