(a) Standardised parameter estimates of pooled (N = 5) analyses after randomly sampling one independent offspring from each litter and model averaging (N = 21,282 individuals). (b) Standardised parameter estimates of pooled (N = 5) independent litter sampling G2+ analyses (N = 16,514–16,516 individuals, see Methods).
