Reverse homeosis in a homeotically reconstructed L. ruber chimera. Over a period of about 3 months, morphogenetic regulation occurred by both intercalary regeneration and compensatory transgeneration. The postocellar region was restored by intercalary regeneration behind the posterior ocellar region. The compensatory regression occurred in the anterior ocellar region leading to the degeneration of the syngeneic eyes. Pictures were taken at: 1 week (A), 3 weeks (B), 6 weeks (C), and 14 weeks (D) after the homeotic reconstruction. (Scale bar: 300 μm.)
