With a sample of 524 pairs of three to eight year old twins recruited from a popula- tion registry, sibling cooperation and conflict were linearly related to the level of temperamental difficult - difficulty expressed in the twin dyad. Heritability accounted for 75% of the variance in Difficult Temperament, 0% of the variance in Instigating Cooperation, and 41 % of the variance in Instigating Conflict. The shared environ- ment, on the other hand, accounted for 0% of the variance in Difficult Tempera- ment, 6 1 % of the variance in Instigating Cooperation, and 28% of the variance in Instigating Conflict. Genetic influences largely accounted for the association be- tween temperament and the sibling relationship. Using identical twin difference scores, Sibling Cooperation was one aspect of the nonshared environmental influ- ence on temperament. Parental Positivity and Parental Negativity predicted the sibling relationship above and beyond temperament. Thus, the behavior genetic design elucidated the etiological distinctions among these correlated family vari- ables
