Oh, there are some pretty interesting resemblances in my family...
For one, almost EVERY descendant of my paternal great-grandmother has her eyes, including me.
But the weird stuff comes in on my mother's side. Some traits have an odd habit, it seems, of skipping and appearing on opposite sides of the family.
I seem, for instance, to have a VERY disproportionate amount of DNA from my maternal grandfather. So many things in my appearance, personality, even medical profile, are straight from him that it's scary. And NONE of these traits manifest in my mother (nor, for that matter, my dad or his family), yet magically decided to make a dramatic appearance in me.
It gets even funnier when you bring my first cousin into the picture, on that side of the family. If all you could see were the mothers, you'd think that the two of us got swapped somehow: I look like my aunt, and my cousin looks like my mom. When you bring in the fathers, though, it becomes clear who belongs to who--but without that, I can almost guarantee people would get it wrong.
(Oh, and to whoever posted that pic of the two cousin kings--that is creepy! I'm going to bring that out next time anyone says the Macet/Dukat cousin theory that's been established in the Treklit is too preposterous or soap opera like...I mean, look what happens in real life!)
