Figure 3: Developmental plasticity of vertebral number in response to incubation temperature.
From: Causes and consequences of intra-specific variation in vertebral number

Figure shows genotype by environment interactions as indicated by within-family comparisons of vertebral number in Esox lucius pike reared under three temperature treatments. Figure shows means ± s.d. Symbols indicate data for five split-brood families originating from subpopulation O. Data on temperature have been jittered in the x-axis direction.
