In the F2 generation, morphological effects such as body shapewere still apparent in larvae whose grandparents were fed BaP(Fig. 2C and D), and in fact, dietary BaP exposure had an effect onbody shape, tail shape and pectoral fins (Fig. 3B, C, and D). Incidenceof normal body shape was significantly lower in the F2 medium andhigh BaP dose groups (82%) than in control (100%), and mild defor-mity incidence (score 3) was significantly higher (18%) in the F2medium dose group than in control (Fig. 3B). The F2 high dose groupwas the only group with moderate (score 2) and severe (score 1)body shape deformities but their incidences were not statisticallysignificant. The F2 high dose group also had a significantly lowerincidence of normal tail shape and normal pectoral fins (Fig. 3C andD). Moreover, moderate and severe deformities were only observedin the medium and high dose groups.
