Principal component analyses of genetic structure between mother and offspring from family P1 (a) and family P2 (b) reveal a pattern consistent with multiple paternity of offspring. In both cases, the mother (enlarged black dot) is positioned between two offspring clusters (open dots) that are separated along principal component axis 1. For a follow-up assessment of relatedness (Additional file 1: Figure S2), we consider individuals with PC axis 1 values less than the mother to be putative full sib group 1, and those with values greater than the mother to be full sib group 2
