Abstract excerpt
Body-colour polymorphism is closely associated with fitness variation and environmental adaptation in insects, yet the genetic and physiological significance of rare colour morphs remains poorly characterized. During field surveys, we discovered a wild parthenogenetic yellow morph of the pea aphid, Acyrthosiphon pisum, and examined its inheritance pattern, fitness performance, and heat-stress physiology....
