A model of quantitative-genetic variation in developmental processes is introduced and analyzed. The model is of a bifurcating sequence of events in which traits develop from the same tissue until a transition occurs, after which they develop partially independently. Genetic and environmental variation in both the rates of tissue growth and in the timing of transitions is considered. The model shows how genetic variation in developmental parameters governs variation and covariation in phenotypic traits and how selection on the phenotype alters the distributions of developmental parameters. Particular attention is paid to the conditions under which selection will lead to changes in the average times of developmental events.
引入并分析了发育过程中数量遗传变异的模型。该模型是一个分叉的事件序列，其中性状从相同组织发育，直到发生转变，之后它们部分独立发育。考虑了组织生长速率和转变时间的遗传和环境变异。该模型展示了发育参数的遗传变异如何控制表型性状的变异和协变，以及对表型的选择如何改变发育参数的分布。特别关注选择导致发育事件平均时间变化的条件。
