An interactive visualization where users input MZ and DZ twin correlations using sliders. The calculator displays the estimated broad-sense heritability, shared environmental component, and non-shared environmental component using Falconer's formula and an ACE model decomposition. A bar chart shows the relative proportions of genetic and environmental variance. Preset buttons load real twin study data for traits like height, BMI, and schizophrenia.
