Species-specific description: Shen et al. (2023): "To determine the functional role of Cyp19a1 in turtle ovarian determination, we established loss- and gain-of function models through in ovo lentivirus-mediated genetic manipulation. ... our results suggest that Cyp19a1 is both necessary and sufficient for ovarian determination in the red-eared slider turtle, establishing causality and a direct genetic link between aromatase and reptilian sex determination and differentiation." This phene includes references to studies involving gene edited or genetically modified organisms (GMO).
