A schematic illustration of hypothesized difference in genetic architecture of morphological and life history traits. L depicts some life history trait, M1–3 refer to morphological traits which all have their underlying additive genetic (V A i) and environmental (V E i) components. Variation in life history traits arise as the summed effects of variation in morphological traits, and is in addition influenced by environmental variation influencing the life history trait directly (V EL). For sake of simplicity, correlation between different traits is ignored. Modified from Price & Schluter (1991).
