Can identical twins have different hair and eye color and still be identical? Me and my twin sister are almost exactly identical in every way except our hair and eye color. I have blond hair and gray-blue eyes, and she has light brown hair and gray-green eyes. Our doctor says we are identical but no one thinks we are because we have different an eye colors. So if anyone knows if identical twins can be identical even if they have different hair and eye colors i'd love to know what you think. Update: we are both girls by the way.
The stereotype of identical twins is that they are exactly the same: they look alike, they dress in matching outfits, they share the same likes and disklikes. Parents of identical twins know differently, however. Despite their shared genetic component, identical multiples are unique individuals. Though they do share similarities, they also have many differences. For example, my own children have always exhibited about a twenty-five percent difference in their weight.
