Biometrical genetic analysis of the cotwin control design.

Behavior genetics - 1 Jul 1994

Duffy D L

Abstract excerpt

The twin-cotwin matched case-control design can be interpreted in terms of bivariate genetic factor models. I derive expressions for the expected intrapair difference for a trait correlated with the variable on which discordance was selected.
