Fig. 2From: Implications for introgression: has selection for fast growth altered the size threshold for precocious male maturation in domesticated Atlantic salmon?Weight frequency distributions for: all strains (a), wild (b), hybrid (c), and domestic strains (d). The vertical stippled line indicates the predicted average size threshold between the lower and upper mode for the wild (19 g), hybrid (26 g) and domesticated (26 g) strains in these data.
