people used to say to look at the uncles on your mum's side of the family, but even your father's side genes will also affect you.
here's a passage from wiki:
Recent research confirmed the X linked androgen receptor as the most important gene, with a gene on chromosome 20 being the second most important determinant gene (snpedia). This research suggests that heredity of AGA is X linked, however, research has also shown that a person with a balding father has a significantly greater chance of experiencing hair loss. Men whose fathers had experienced hair loss were 2.5 times more likely to experience hair loss themselves, regardless of the mother's side of the family, which may suggest Y linked heredity plays a role.[17][18]
