Have first generation Italian friends who have a blond, blue-eyed, light skin son, and their other son has black hair, dark eyes, and an olive skin tone. They told me that Northern Italy has more genes from the Germanic and Nordic gene pool, while the Southern Italians have darker skin, etc., going back to the Moor/Arab invasions. Also, since Southern Italy is more rural, from working more outdoors. Also have Hispanic friends whose family comes directly from Spain, and they are blue-eyed blonds, not the dark haired, darker skin Hispanics that many of us think of generally as Hispanic. Just looking at someone is meaningless...as someone said, genetics is interesting but totally unpredictable.
