纵向行为遗传学研究提供了一个机会来分析发育变化和连续性，这是发育行为遗传学解决的两个基本问题。纵向分析可以看作是多变量分析，因此受益于该领域最近取得的进展。此外，遗传相关性和双变量遗传力的主要多变量概念在纵向分析中具有更大的意义：它们意味着年龄与年龄之间的遗传连续性和变化。本文讨论了多变量分析和纵向分析之间的关系，在分子遗传学和定量遗传学水平上考察了年龄-年龄遗传变化的意义，并在科罗拉多收养项目的亲子数据背景下考虑了年龄-年龄遗传变化对家族相似性的影响，该项目可视为从婴儿期到成年期的“即时”纵向研究。
Longitudinal behavioral genetic studies provide an opportunity to analyze both developmental change and continuity, the two essential issues addressed by developmental behavioral genetics. Longitudinal analysis can be viewed as multivariate analysis, thus profiting from recent advances made in that area. Moreover, the major multivariate concepts of genetic correlation and bivariate heritability assume added significance in longitudinal analyses: They connote age-to-age genetic continuity and change. In this paper, the relationship between multivariate and longitudinal analyses is discussed, the meaning of age-to-age genetic change is examined at the level of molecular genetics as well as quantitative genetics, and the implications of age-to-age genetic change for familial resemblance are considered in the context of parent—offspring data from the Colorado Adoption Project, which can be viewed as an “instant” longitudinal study from infancy to adulthood.
