A prey animal has the alternative of fleeing or feigning death to survive when it encounters predators. We found that fleeing by an artificial threat, locomotion and feigning death are pleiotropically correlated with a genetic factor related to a biogenic amine in the red flour beetle, Tribolium castaneum . Walking distance of adults was significantly lower in strains artificially selected for longer (L strains) than shorter duration (S strains) of death-feigning. Crosses showed that S-strain… CONTINUE READING
