The "heritability" of a phenotype measures the proportion of trait variance due to genetic factors in a population. In the past 50 years, studies with monozygotic and dizygotic twins have estimated heritability for 17 804 traits; thus twin studies are popular for estimating heritability. However, overestimation of heritability in twin studies is one suggested cause of the "missing-heritability phenomena" (estimates from empirical genetic studies are often smaller than twin studies). Developing more accurate methods for estimating heritability may be warrant
