Abnormal embryonic development induced by parental BPA treatment. The morphologies of normal embryos from control (Control) fish and abnormal embryos from BPA-treated fish in generations F1 to F3. Photographs of three representative phenotypes of abnormal embryos in each generation are shown. Most of the embryos died from coagulation before hatching. Approximately five to fifteen percent of the surviving embryos exhibited abnormalities in all generations. It was observed that several abnormalities, including skeletal spine curvature (ssc), cardiac edema (ce), problems with yolk sacreabsorption (ysr), non-detachment of the tail from the yolk (dty), and double-head (dh), occurred randomly in individuals.
