Descriptive statistics for male LRS and LAFf measured across (A) banded offspring, (B) adult offspring, (C) banded grand‐offspring, and (D) adult grand‐offspring across 101 adult male song sparrows that formed at least one social pairing, and the SD‐standardized selection gradients (β, with 95% bootstrapped confidence intervals, 95% CI) of w‐standardized LRS and LAFf on the mean coefficient of kinship with the socially paired females with which each male made its breeding attempts (ƙmate) and on the male's own coefficient of inbreeding (f)

IQR = interquartile range. Bold signifies selection gradients whose 95% CIs did not overlap zero.
