Mean (SE) numbers of lateral plates and pelvic scores on the left and right side, along with number of individuals sampled (n) for wild-caught and laboratory-bred and reared individuals, crosses between different low-armor populations (F1 complementation), hybrid F1 individuals produced by crossing low-to complete-armor fish (F1 mapping), and the offspring of full-sib crosses between F1 mapping individuals divided between complete and low lateral plate and pelvic classes (F2 mapping). Bold indicates scores within the complete-armor class.
