VAB does not segregate with sleep or locomotor activity in hybrid or outbred cavefish populations. (A) F₂ and F₃ hybrid fish were generated from a female surface fish and a male Pachón cavefish. Hybrid fish were then tested for vibration attraction behavior (VAB) followed by locomotor activity (B-D). No correlation was observed between VAB and locomotor activity (B), sleep duration (C) and bout number (D) (P >0.05). (E-G) Pachón cavefish were assayed for VAB and locomotor behavior. No correlation was observed between VAB and locomotor activity (E), sleep duration (F) and bout number (G) (P >0.05).
