This study generates a series of narrow‐sense heritability estimates for crown morphology of the deciduous and permanent dentition with two overarching aims. The first is to test the hypothesis that deciduous teeth provide a more faithful reflection of genetic information than their permanent successors. The second is to use quantitative genetic methods to evaluate assumptions underlying common data collection and analysis practices in biodistance research.

人类双歧齿牙复合体的遗传模式：澳大利亚双胞胎和家庭的冠状形态。

这项研究针对落叶和永久性牙列的冠状形态生成了一系列狭义的遗传力估计，其目标是两个主要目标。第一个是检验以下假设：乳牙比其永久继承者更能忠实地反映遗传信息。第二种是使用定量遗传学方法评估生物距离研究中常见数据收集和分析实践的基础假设。
