From: Heritability and genetic correlation between the sexes in a songbird sexual ornament
Relationships of standardised size of the ornament in adult offspring of both sexes on those of their fathers and mothers. Lines are fits from linear regressions, with regression coefficients (b) indicated in each case. Note that doubled b coefficients do not equal heritabilities in Table 1 due to the latter being corrected for assortative mating with respect to FP size.
