评估了为应用于正在进行的科罗拉多收养项目中收集的数据而开发的遗传和环境传播路径模型。除了提供遗传和环境影响的测试之外，该模型还包括被动基因型-环境相关性、父母对孩子环境的影响、选型交配和选择性安置的参数。使用最大似然法从一岁和两岁儿童、他们的亲生父母和养父母以及对照家庭成员的心理能力数据中获得参数估计。模型与数据的拟合令人满意。获得了对遗传影响的高度显着估计和对家庭环境的显着测量。通过将完整模型的拟合度与删除了选择性放置参数的简化模型的拟合度进行比较，确认了选择性放置的不存在。尽管发现了一些可能的基因型与环境相关的证据，但它占总方差的比例相对较小。
A path model of genetic and environmental transmission developed for application to data collected in the ongoing Colorado Adoption Project was evaluated. In addition to providing tests of hereditary and environmental influences, the model includes parameters for passive genotype‐environment correlation, parental influences on the child's environment, assortative mating and selective placement. A maximum likelihood method was used to obtain parameter estimates from mental ability data on one‐ and two‐year‐old children, their biological and adoptive parents, and members of control families.There was a satisfactory fit of the model to the data. Highly significant estimates of genetic influence and a significant measure of home environment were obtained. By comparing the fit of the full model to that of a reduced model in which selective placement parameters were dropped, the absence of selective placement was confirmed. Although some evidence for possible genotype‐environment correlation was found, it accounted for a relatively small proportion of the total variance.
