Genetics would not impart all personalities, but generally would impart many autistic spectrum traits - which covers a large swath of social interactions - however keep in mind autism is so many genes that a parent may have a completely different reaction to something than their child, and the fact that there is a second gene pool. For the most part, those genes have massive effects on hormone levels during development which has a huge affect on personality. In general this is why the linkage between personality and heredity is so hard to track.
