In brief: Higher risk

A study in the lancet (2009) showed that if sibling a has bipolar, the sibling b is 8 times more likely to develop bipolar disorder.
Other studies place the relative risk range between 7 and 10 times. This translates to a 5-20% risk.

In brief: Small

Small but greater than chance.
Although there are genetic predispositions in the development of bipolar disorder it clearly is not the significant determiner.
