Examination of M suggested that both juvenile and adult traits in maternal plants influenced the expression of offspring traits. Seed size was influenced exclusively by maternal environmental effects, whereas maternal genetic effects influenced traits throughout the life cycle, including strong direct and maternal additive genetic correlations within and between generations for phenological and size traits. Following a three-generation breeding design, we grew paternal half-sib families with full-sib relatives of each parent and measured juvenile and adult traits. Here, we used multivariate genetic models to estimate the contributions of maternal and direct genetic (co)variance, the cross-generation direct-maternal covariance, and M, the matrix of maternal effect coefficients, for life-history traits in Campanulastrum americanum, a monocarpic herb. Less is known about the prevalence of genetic maternal effects and how they influence adaptive evolution. In plants, most work has focused on the effects of maternal environments on offspring trait expression. Maternal effects are ubiquitous in nature.
