A complex segregation analysis was performed on Carabelli's trait on the upper first molar utilizing 358 nuclear families from the Solomon Islands of Bougainville and Malaita. Simultaneous estimation of three sources of variation by the method of maximum likelihood demonstrates a significant effect of shared sibling environment which accounts for over 19% of the variance in liability for the trait. In addition, a statistically significant major gene influence is discussed and suggestions for quantifying individual liability levels for this and other dental traits are outlined.
利用来自布干维尔和马莱塔所罗门群岛的358个核心家庭，对上颌第一磨牙的卡氏特征进行了复杂分离分析。通过最大似然法对三个变异来源进行同时估计，结果表明同胞共享环境具有显著影响，该环境占该特征易感性变异的19%以上。此外，还讨论了具有统计学意义的主基因影响，并概述了量化该特征及其他牙齿特征个体易感性水平的建议。
