This is fun to think about, but yes, a child can look like neither biological parent. It's not something people tend to expect, but it's possible to inherit Great-great-grandma's hair color and Great-grandpa's nose instead of Mom's and Dad's. Just as with talents, physical characteristics can pop up after several generations.
And yes, some Italian people don't look like what we think Italian people should look like. When we visited northern Italy years ago, some Italians we met looked more as if they were Swiss.
I have four children, and three of them are undoubtedly our kids! The resemblance is unmistakable. The other - well, we wondered who she took after, but as she grows older (she's in her 30s now) she's looking more and more like various relatives on both sides.
My niece and her husband have four daughters. Three have beautiful brown hair and brown eyes like their parents. The oldest girl has blue eyes and natural blonde hair to die for! Yes, there are those genes further back in the family. Who'd have believed they'd make a reappearance!
