Fig. 2. Hybrid incompatibility caused by the interaction between a transcription factor and
its binding sites. A transcription factor and its binding sites co-evolve independently in each
isolated population. The transcription factor of species X may not be able to bind to the
binding site of species Y, which results in the failure of transcription regulation in the hybrid
