Venn diagram representations built using the same data shown in Table 3 of Iqbal et al.’s study [6]. Numbers inside the balloons represent the genes with altered DNA methylation in each generation (G1 or G2), in sperm or MGC, in response to each exposure tested (BPA, DEHP, or vinclozolin). The intersections between the G1 and G2 generation balloons show the number of common genes epigenetically altered in these two generations in response to the different exposures
