I am a lot like my father in the ways I act and the fact that mom, my sister and my brothers swear I have dad’s “the look”, i.e. the “I can see right through that bs you’re trying to hand me” look and I’m left-handed just like him. As far as looks, I didn’t look like either side of the family so long ago had decided my father must be the postman or milkman. 
Ok, I thought that until several years back when I saw a picture of my great grandfather (mom’s grandfather) and it was like looking at myself.
Actually, neither . . . but if I have to pick one, it’s my mother’s side, even though I’m the “black sheep.” My father’s family is basically Jewish white trash, and I’m happy having nothing to do with them.
I look just like my dad’s side of the family and did even more when I was little. Pictures of me when I was about 5 or my aunt at the same age could be confused for each other except that pictures of her are black and white and mine have lovely '80s attire.
In personality I’m much more like my mom, but hopefully not too much like her family, who are unpleasant, occasionally racist, sometimes unethical, and generally not very nice. Their idea of humor usually involves putting someone else down. I haven’t seen anyone on that side of the family since my grandfather’s funeral, and my husband has never met them at all. I’d be ok if we kept it that way.
Mom’s side, without a doubt. I was well into adulthood when I met my dad and his side and we had almost nothing in common.
Very, very like my father’s family, physically - I look far more like my aunt than like my mother. But people who know both of us swear that my mother and I look identical, even though we share almost no physical similarity. Personality-wise, I had no choice but to be stubborn - go that from both sides. All of the women in my mother’s family sound alike, which is kind of odd sometimes. From my father’s side, definitely brains, introversion, and a fair bit of “independent-mindedness”/eccentricity. My personality isn’t much like anyone in Mom’s family.
All three of us take much after my dad in personality, interests, etc. We don’t know any of his biological relatives and we’re the black sheep of my mom’s family (they are conservative, Democrat, super-Christian academics obsessed with ‘appearances’ and the proper way to do everything - my sisters and I are radically liberal, apolitical, atheist, high-school drop-outs who do what we want and ignore many rules).
That depends on who you ask. My father’s side is always claiming me or my kids ‘look/act/sound just like your father.’ Since he left when I was 5, I have no idea. I sometimes think they just want to see that in us, especially since he died a few years ago.
My mother is always saying my and mine look/act/sound like a Pratt (mom’s maiden name).
I do know my temper, body type, stature, love of reading and sometimes questionable sense of humor comes from my Mom’s side of the family.
I believe I must get my curiosity, wanderlust and sense of adventure from my father’s side.
Physically, I’m a bit of a mixed bag - I have my father’s curls, my maternal grandfather’s face shape, shortness that could come from either one of my grandmothers, and the nose and smile of my paternal grandmother. And my mother’s unusually rapid heartbeat.
In other ways, I’m most like my mother’s family. At least half my relatives on that side work in the medical field, most of them are musical, and we tend to be nerds with a strong goody-goody streak who love to travel. I have less in common with my father’s family in general, but I do see bits of myself in several relatives on that side.
Yesterday I cut my hair, from mid-back to really short.
With it combed down, I look like Middlebro, which isn’t saying much… with it messed up, like my mother’s sister.
My brains on the other hand appear to come from Dad. There have been people who have realized I must be related to him after hearing me perform a logical analysis; there have been people who have told me “you must get your face from your mother, but what’s behind is your father’s.” I happen to like Dad’s side best, so I’m fine with that.
Physically, my mom’s side. I was amused recently when my aunt scanned some old pictures and posted them on Facebook; if you waxed my eyebrows and stuck a beehive wig on me, I’d look exactly like her. We also have the same glum look when we think we have a blank expression. There’s a photograph of her decorating a Christmas tree, and everyone was commenting on how sad she seemed in the shot, while I was happy to see that I carry on yet another trait.
I think my academic side comes from my mom’s side of the family. All of my cousins on that side are fiercely intelligent, my uncle is very intelligent… my mom can be, but she had the misfortune of being a single mom in the 1960s and 1970s, so never got to continue her education.
Mental illness? Mom’s side as well. Depression looms large for all of us, and the family tree has been judiciously self-pruned over the years.
Alcohol use? Dad’s side of the family. Thanks, dad.
Bit of both - Got my stuborn streak for my mothers side (Pure Scott) and the Talkative side from My Father (Itallian Irish) and the social side from both 
I’m really almost pure Ciccarella (mom’s side). I don’t think I get much other than genetics from the Grays. My father was never close to his siblings, and I seem to have inherited that (I haven’t spoken to my brother since just after my mom’s funeral last year…no animosity or anything…we just don’t keep in touch). I think I inherited my wise-assness and my indifference to matters of religion from that side, too. Everything else, from the Italian looks to the worrying to the indecision to the tendency toward overweight to the slightly nasal voice, I got from my mom’s side.
Appearance wise, I’ve often been told I look just like my mother.
In other respects, however, I take after my father’s side.
My hair is going gray–not dramatically, yet, but significantly, and I’m not yet 40.
My grandmother had a fear of heights, supressed through power of will, and me, I don’t like ladders. All three sons and at least two grandchildren admit to some degree of lack of fondness for heights. I’m not sure my brother does, but his wife does on his behalf.
I fear I inherited some of her stubbornness, but I hope her inability to age gracefully was not passed on.
I look strikingly similar to my mother. Comparing pictures of her as a kid to my childhood pictures, we look like the same person. Except the clothes/hair/photo-quality are dated. But in temperament, I’m much more like my father and his sister. Reserved, introverted, quiet as a mouse, don’t keep in touch with family, and lots of social anxiety… until I’m around friends. Then I loosen up.
As far as extended family is concerned, I’m really not like either side. The women on both sides of my family (with the exception of my father’s sister) tend to be extremely large, extremely viviparous, and extremely smart yet unmotivated to make their own way in life. They enjoy raising their many children with the help of a sugar daddy or the federal government.
As to why I’m not like either side, I think that my dad’s dad (who died about 13ish years ago) has passed on some extremely fucked-up genes and behaviors. He was an alcoholic, a diagnosed schizophrenic, and he beat up and threatened his wife and kids at gunpoint on a regular basis (which my father did to my mom once, and beat her regularly, and he also abused me sexually, so…). I think my paternal grandfather explains why I and my sister are so different. I don’t know if it goes back further, I don’t know anything about my grandpa’s dad because they’ve all been dead for a long time.
At any rate, I’m happy that his genes will be dying with us.
I’m a mixed bag.
I take after my paternal grandmother in build (although not as tall), my mother in skin tone and my father in hair and eye color.
Personalitywise? I get the sense of humor, musical and artistic ability and “shit happens” attitude from Mom’s people. I get an understanding of how things work, craftmanship, logic and sense of quality from Dad’s side.
It could be worse. I could get Mom’s logic and sense of quality and Dad’s musical and artisistic ability. 
Vivacious, perhaps? Because pretty much all mammals, short of monotremes, are viviparous.
Mostly I take after my mother’s side.
Physically I’m a lot like my dad, but my face is more like my mom’s family’s. I used to look a lot more like my dad when I was little, but when puberty hit my nose and chin changed to look more of the other side of the family.
Personality and mental abilities are more like mom’s side too. I love my dad, but he’s not terribly bright; mom’s side has most of the brains. I share the general pessimism and sharp sarcastic wit with them too.
But, I learned how to be a pretty decent human being from my dad, despite his less attractive personality quirks, which are probably a product of his upbringing. He seems to be a bigoted asshole, and he’s deliberately provocative sometimes (I’ve figured out that he does that when he feels like he needs to control the conversation; anger is the easiest emotion to manipulate) but he’s solidly trustworthy if you need something done, and however much he may throw around the words “nigger” and “wetback” in private, he’s the first guy to go out of his way to help someone…including anyone who could be described as a nigger or wetback. His mouth doesn’t match his actions, and I seem to have picked up on the lessons he demonstrated, rather than what he said.
ok, my mom is short 5’2"bio father is 5’8", so neither–i am tall iwould say more like i resemble
bio grandmas looks(heighth)and bio-aunts heigth also but otherwise i totally resemble birth moms side of family
and then i DO have biosTEMPER /
and addictive/ abusive traits . uhhhhhh- my bad…
I definitely take after my father. Physically and temperamentally.
