回答: 你很可能没有明白孪生子研究是怎么做的 由 方舟子 于 2007-04-30, 14:40:41:

The experiment compares the correlation between identical twins and between fraternal twins. It is assumed that identical twins are twice as genetically similar as fraternal twins. The heritability is then calculated as twice the difference betweent the two correlation coefficients.

Obviously, what measured is a correlation.
