Descriptive statistics for female LRS and LAFf measured across (A) banded offspring, (B) adult offspring, (C) banded grand‐offspring, and (D) adult grand‐offspring across 99 adult female song sparrows, 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 males with which each female made its breeding attempts (ƙmate) and on the female's own coefficient of inbreeding (f)

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