On my side of the family, there is Morton's toe. Also known as Celtic toe, and that would be where it comes from in my familly. The second toe is longer than the big toe. I have it, and I think both of my siblings have it. We also have, from my dad's side, some double-jointed fingers. Which isn't really useful for anything except grossing my mom out. Oh, and we can all roll our tongues, which I believe is genetic. Ds1 can triple roll his.
On dh's side of the family, they have a lot of recessive traits. Both of dh's parents have red hair, and all of their kids have had red or strawberry-blonde hair. Dh's dad's hair has darkened to almost brown, and dh's is on the way there. I'm not sure about dh's siblings, but I know he doesn't have a widow's peak and he has attached earlobes, and those (IIRC) are both recessive traits. I know at least a few of his siblings have the same ears and no widow's peak, but I don't know about all of them. None of the kids have attached earlobes, and I think they all have widow's peaks, too.
I was taught that those were recessive in first year bio, but now, wikipedia is disputing that. So, who knows.
Dh has wavy red hair & green eyes. I have wavy/curly brown hair and I may have either blue or green eyes. I think they're more blue, but I sometimes get told they're green. I think it depends on what I'm wearing.
As for who our kids resemble:
Ds1 -- clone of dh, but my face shape. Blue eyes, hair started off blond but is now brown
Ds2 -- strongly resembles some of dh's siblings. Dark green eyes, blond hair
Dd -- doesn't really look like either of us, or anyone else in our family, though I think she resembles my maternal grandmother. Born with straight black hair & blue eyes, now has wavy blond hair and green eyes.
Ds3 -- clone of dh, but with my face shape. Blond hair (was strawberry blond), blue eyes
Ds4 -- clone of my mom's dad, brothers, and my cousins on that side. Starting to resemble me more, though. Blue eyes, curly auburn hair.
