Quizplus · Accepted Answer

Research has consistently shown that bipolar disorder has a stronger genetic contribution than unipolar disorder. Twin studies have shown that bipolar disorder has a heritability rate of around 80%, while unipolar disorder has a heritability rate of around 37%. This suggests that there are genetic factors that are more strongly involved in the development of bipolar disorder than unipolar disorder.
