Abstract
It was hypothesized that heritability estimates based on a simple additive model of environment and heredity would be spuriously high if there were actually an interaction between them. Results of a musical aptitude test given to twin pairs with different amounts of music lessons indicated higher heritability compared to twin pairs with the same amount of music lessons. It is logical to assume that interaction of environment and heredity produced the higher heritability estimate.Keywords
