Fig 5. Expected distribution for quantitative trait differentiation between the Spanish and Northern European population.

Qst. The expectation is based on a multivariate normal distribution assuming a neutral trait with polygenic basis. Vertical lines indicate observed Qst for the individual growth parameters, FS (Solid line), t50 (Dashed line), Slope (Dot line), in HL (orange) and LL (cyan). The red arrows show the 90^th, 95^th and 99^th percentiles of the distribution.
