Erratum to: Behav GenetDOI 10.1007/s10519-013-9625-7

On the third page of the article, first paragraph, the A and D factors in DZ twins are incorrectly stated to correlate 5 and 25, respectively, instead of .5 and .25. The correct sentence is thus: “Based on quantitative genetic theory (Falconer and Mackay 1996; Mather and Jinks 1971), the A factors are known to correlate 1 across MZ twins and .5 across DZ twins, and D factors are known to correlate 1 across MZ twins and .25 across DZ twins.”
