The equality of means of continuous variables by zygosity was tested using all adjusted Wald test (using the Stata svymean statistical program ([dagger])) to take into account that the twin individuals had been sampled as twin pairs and thus did not represent fully independent observations.
In our study, covariance matrices for the two zygosity groups were subjected to structural-equation modeling with the LISREL 7 program (17) to estimate the genetic and environmental components of variance.
These twins of unknown zygosity are then subjected to a series of tests by genetic markers (e.
