Fig. 3From: Despite genetic isolation in sympatry, post-copulatory reproductive barriers have not evolved between bat- and human-associated common bedbugs (Cimex lectularius L.)The offspring size as the pronotum width in mm for each population cross. The coloured symbols show population means and the lines show means for lineage crosses with the dashed lines representing one standard error. The female populations are denoted on the x-axis and the colors represent the male populations. The error bars represent one standard errorBack to article page
