From the BBC:
Scientists can now answer the question, following the first study of a polar bear/grizzly bear hybrid.
Only one hybrid bear has ever been seen in the wild, so the study evaluated two hybrid bears kept in captivity, which are among 17 such bears known to exist.
While each hybrid has inherited characteristics from either parent, some traits, such as partially hollow hair, appear to be a blend of the two.
“Hybrids between polar and brown bears in the wild are very rare. Only one confirmed case is known,” says Dr Ute Magiera, the conservation coordinator of Osnabruck Zoo in Germany.
That hybrid bear was shot in April 2006 by an American big game hunter on Banks Island, Northwest Territories, Canada.
