Bipolar disorder is a psychiatric illness with a strong hereditary basis,but the exact mode of its inheritance is not known. Research has shownthat siblings of patients with bipolar disorder are more likely to developthe disorder than are siblings of unaffected people. Findings from onestudy demonstrated that the ratio of bipolar brothers to bipolar sisters ishigher when the patient is male than when the patient is female. In otherwords, relatively more brothers of patients with bipolar disorder alsohave the disease when the patient is male than when the patient isfemale. What does this observation suggest about the inheritance ofbipolar disorder?

Question
Bipolar disorder is a psychiatric illness with a strong hereditary basis,
but the exact mode of its inheritance is not known. Research has shown
that siblings of patients with bipolar disorder are more likely to develop
the disorder than are siblings of unaffected people. Findings from one
study demonstrated that the ratio of bipolar brothers to bipolar sisters is
higher when the patient is male than when the patient is female. In other
words, relatively more brothers of patients with bipolar disorder also
have the disease when the patient is male than when the patient is
female. What does this observation suggest about the inheritance of
bipolar disorder?
