Mean ± 1 SD (and range) of the difference in total brood allelic value E(a), carrier probability P(C), allelic value per copy E(a|a), and allelic variance var(a) across (A) 420 broods that contained only within‐pair offspring (WPO‐broods) relative to their mother versus father; (B) 321 broods that contained at least one extra‐pair offspring (EPO‐broods) relative to their mother versus her socially‐paired male; (C) 321 potential WPO‐broods versus observed EPO‐broods relative to the mother's socially‐paired male; and (D) 321 potential WPO‐broods versus observed EPO‐broods relative to the socially‐paired male given no inbreeding
