Binet For Twins

How to Use BET for Twins to Evaluate Assortative Mating and GE Correlation

Due to the unique environment interaction, twin studies can be biased. Random mating of identical twins can lead to lower estimates of heritability and increase the effects of shared environmental influences. The classical twin design, however, includes the parents of the twins. This may allow researchers to evaluate assortative and GE correlation. Furthermore, MZ sum and difference scores are able to detect assortative mating.
