Diabetes and heart disease on my father's side, and ovarian cancer on my mother's. My double 2nd cousin just got diagnosed with ovarian cancer last year, and was found to have an uncommon cancer gene. I have not yet been tested, and the test is pricey, and cannot be done locally. Baldness, from my maternal grandfather. Neither his father nor grandfathers seemed to have it, so he may have inherited it from his mother's family, which I have no photos of. He went bald in his 20's, as did his son. My brother went bald in his 30's. Red/Green color blindness. From same grandfather. My brother got it, too.
Both sides of my family tend to be night owls. Mostly even tempered, intelligent, with a lot of musical talent, the latter of which I did not inherit. My mother's side of my family tends to have a long face. I inherited my father's round face, and my mother's nose and voice. And shyness, on my mother's side. Many of us are painfully shy and have to learn how to grow out of it as we mature. Both sides of my family are pretty scientific--biologists, chemists, doctors, computer geeks, engineers, etc.
