  1. Sampling Sites, total number of genotyped specimens and numbers in genotypic classes used for this study. The individual genotypic classes were inferred from microsatellite data and served to group specimens for morphometric analyses. Specimens excluded from the analysis include later generation backcrosses or those for which morphometric data could not be obtained. Note that there are sampling sites at which all genotypic classes occur syntopically.
