Analyses were performed using a full-sib design and accounting for population inbreeding.
N = sample size, Nfam = number of families, Vb and Vf indicate between population and family variance, respectively. Gompertz growth parameters: A is asymptotic size, b is related to size at birth, k is related to growth rate. Left and right P-values indicate the probability for QST-FST observed value to lie within the neutral distribution (unilateral test based on 1000 bootstraps, α = 0.025).
