Fitting genetic models to Carabelli trait data in South Australian twins.

Journal of dental research - 1 Feb 1992

Townsend G C, Martin N G

Abstract excerpt

This study aimed to clarify genetic and environmental contributions to Carabelli trait variation on permanent first molar teeth in a large sample of South Australian twins. Estimates of polychoric correlations were obtained between pairs of monozygous (MZ) and dizygous (DZ) twins for Carabelli data and various gene-environment models fitted by a weighted least-squares approach. The favored model included additive...
