From: The genetic architecture of hybridisation between two lineages of greenshell mussels
Sigmoidal cline plots for the 10 alleles showing greatest change in allele frequency as a function of latitude. In each case, the cline fit is based on data from 12 populations; the HSB population (circle ○) and the BGB population (black triangle ▴) shown for comparison. The hybrid zone is located in the areas of steepest gradient of change of allelic frequency. Note the different y axis ranges that are necessary to show detail of the sigmoidal curves.
