[Heritability index for diagnosing talent and aptitude in children and teenagers]

Longitudinal correlation und heritability in the broad sense are equivalent expressions for the reliability in the long run. Since long-range prediction is the aim of personnel selection in athletics, education and other applied fields, we recommend to use heritability as a weighting factor for phenotypic scores of adolescents in order to calculate true scores and to eliminate error variance. On the basis of the matrix of correlations of 7 tests of physical fitness, body height and weight, and their heritabilities the calculation of the heritability index is demonstrated.
