Simulated (bars) and empirical (diamonds) estimates of inbreeding for the Guadyerbas pig population. Mean (F) and variance (VF) of simulated inbreeding coefficients in cohort 23, obtained from true IBD values (FIBD), and estimated from pedigree records (FPED) and from markers (FVR1, FVR2, FYA1, FYA2, FLH1, FLH2, FROH; see text for definitions) assuming the frequencies of the base generation (cohort 17 in a and c and cohort 0 in b and d; blue bars and yellow diamonds), those of the current generation (cohort 23; yellow bars and grey diamonds) or a constant frequency of 0.5 (purple bars). e and f Estimates of the inbreeding depression rate (ΔID) for litter size from 103 females born in cohorts 17–23. The estimate from FPED was obtained from data of 832 females born in all cohorts (0–23). g and h Correlations among simulated inbreeding coefficients in cohort 23. The intervals shown denote 95% of the variation across simulated replicates in order to see if the observed values are within the expected simulated values. Only subscripts of estimators are shown for a better view
