Wierd Science

Genetics are an interesting thing. Are their any traits in your family that are very persistent? For us, blue eyes and big toes are pretty common. Most of us have some form of blondish hair that gets darker as we get older. They're also likely to inherit slightly curly hair from both of us, a golden ring around the iris from my side, loose joints from my side, some freckles and moles, and they'll probably be a little taller than average. What do you think your LO might inherit?

I know most don't have this info, but I figured I'd share. DH and I had our DNA tested this past summer, so we have an idea of what our kids will inherit.

Eyes: 72% blue or gray, 27% green or hazel, 1% brown or black eyes.
Alcohol Flush: 100% won't get the "Asian Flush" from drinking
Bitter Taste Perception: 100% perception of bitter tastes
Earwax: 100% wet earwax (Interesting, because DH has dry earwax.)
Lactose Intolerance: 100% tolerance of lactose
Muscle Performance: 50% endurance (from me), and 50% sprinter (from DH) - This is interesting, because in high school I ran sprints and DH ran endurance.

No testing here, but I love seeing how genetics plays out with our kids.

 

My oldest is an absolute clone of dh, except for being a few shades lighter.  Same physique, same feet, same hair, same nose, same earlobes, same eyes, same nose, same freaking personality, lol.

 

My younger two are a more even mix of the two of us, but they got the earlobes from me, and those particular earlobes are very dominant in my mother's side of the family.  They also have a flatter more typically African nose, even though dh (East African) and me (Euro-mutt) don't have a nose like that.

 

The baby currently baking looks on ultrasound to have a very prominent Roman nose, like dh. :)

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.

Recessive genes are a strange thing by themselves. Sometimes you'll have a trait that is recessive, but it pops up a lot even when it shouldn't. Oddly enough, DH and I both look more like grandparents than our own parents. I look like both of my grandmothers, and my husband looks like his grandfather. DD looks like me, but you can actually see quite a resemblance if you look at pictures of my mom at that age.

My mother's side has what they called "Black Dutch" heritage. It pops up with few kids in each generation. Half of the kids are pale as can be, the other half look like they're from the Mediterranean. My DNA test explained it a little better than my great-grandma. It seems that is actually from a Native American and an African relative. I haven't figured out how far back, but statistically it is likely between 4-10 generations back. I have a lot of very tight curls (pencil width or smaller) mixed in with my mostly wavy hair. It makes me wonder if I inherited that from my African relative, or if it might have come from the Celts in the family.

We only have one child out so far, but my sister has four.

DD1 - No clue who she looks like more. She's got dark blonde hair and hazel eyes.
DD2 - Medium blonde hair and brown eyes. Her hair was reddish to begin with. She looks like her great aunt more than anyone.
DD3 - Really light blonde hair and very fair skin. Blue eyes. Looks like her mom at around that age.
DS - Looks like his daddy. Has reddish-blonde hair and light brown eyes.

With my sisters and I -

Older sis - 5'2", hazel eyes, blonde hair. Her hair was VERY light to begin with, and she didn't have much hair for the first few years.
Me - 5'7", blue eyes with gold ring around iris, brown hair. My hair started as medium blonde and got darker. I was born with a lot more hair.
Younger sis - 5'4", blue eyes, brown hair. Also had medium blonde hair that darkened, but has a HUGE cowlick that nobody else has.

Totally DDCC because genetics fascinate me.I had blonde hair that has gotten sandy and dh has hair so dark brown it's almost black. We have three redheads. One is red, one is bright red, and one is lighter. One with brown eyes, one hazel and one green. There is no one in anyone's memory with red hair.

34me -- how neat!  I figured we would easily get a redhead, since dh is super ginger and I have relatives on both sides with red hair.  Our fifth was our first really red redhead, and even with him, his hair looked black when he was born and it has gradually come in more red/copper.  Dh's sister has 3 redheads, and her dh and everyone in his family has black hair, but his beard comes in red.  My MIL has been so relieved that our kids haven't had red hair, while we've been hoping for it.

 

Cameragirl -- I hadn't thought about cowlicks being genetic.  But they do run in my family; I have two at my front hairline, my sister has one, and 3 of my kids have one.  It makes cutting the boys' hair kind of tricky; I'm already bad enough at cutting their bangs (I don't know if you call it that with short hair?).

Ooooh, I have a Celtic toe!!  Never knew there was a name for that! :D

post #8 of 13

DH was born with an extra finger on one hand, which was remedied easily enough because there was no bone in it.  I had a doctor tell me that extra digits is a very strong trait; she once had a grandmother, mother and daughter who all had an extra toe.  So far, our kids have had 10 and 10, no extra.  Needless to say, my first question (even before asking if it's a boy or a girl) is:  How many fingers and toes?  smile.gif

You know, we could get a redhead as well. My mom has strawberry blonde hair, DH had white-blonde hair that is now light brown, and his beard is blonde and red. We both have a strong family history Scotland, Ireland, Wales, and England, so the genes are there as well.

DH and I share the same main haplogroup. I thought it was really interesting that we picked up the blue-eyed gene mutation very early. It happened at least 10,000 years ago if you believe evolution science. Apparently the group was one of the first to migrate up out of Africa to Europe, where they would have picked up the fair skin, blue eyes, and red hair mutations. What really is interesting is that as Britain got darker during with the pollution during the Industrial Revolution, the red hair genes became very prominent. I've heard that the fair-skinned combo of hair, eyes, and skin might have been an adaptation to allow them to make more vitamin D.

Another strange thing? It only takes five generations for genes to disappear from your DNA. So, Native American ancestry may be gone once you get five generations out. (Or at least what you can see from the current computer modeling.) However, traits can stick around a lot longer somehow. Your grandparents diet affects your metabolism, as well. Survivors of famines have children that have mutated dna that allows for better survival during famines.

I think genetics are fascinating.

I'm mixed race African American (so really, who know what exactly is in there) and Irish.  I have medium toned skin and dark, almost black hair and eyes.  Dh is Irish and has pale skin, sandy blond hair, and light blue eyes.

 

Ds1 is all caramel - tan skin, light brown hair, hazel eyes.  Ds2 is blond, with pale skin and dark eyes.  I can't wait to see what mix we get this time!  I'm hoping for a dark hair/blue eyes combo, which is possible as my grandmother has blue eyes.

 

We all have curly hair.  That's the only shared trait I can think of, I would be really suprised if this baby doesn't have curly hair.

Mixing races produces some wild genetics.  I once met somebody who adopted a half African-American, half Irish son, and he has red hair and has the lightest skin of all the members of this Italian family.  What happened to the African-American genes?

post #12 of 13

My in-laws were the first in either of their families to have a "mixed" marriage. He is half Irish, half Italian. The grandparents are still talking about the scandal 35 years later! In any case, I love comparing him with his siblings. Half of them look VERY Sicilian, and the other half like DH have pasty white skin, reddish hair and delicate features. Without DH's Roman nose you'd never know he isn't fully Irish. So curious to see how our babies will reflect his lineage along with my Swedish chipmunk cheeks. :)

Right?  My ds1 looks like a mix of something, especially in the summer when he's got a nice tan (although then his hair gets lighter than his skin).  But my ds2 looks German.  He's this big sturdy kid with the palest skin and white blond hair.  I'd swear he was switched at birth except he looks just like me - like a bleached out, overexposed me!

 My grandfather basically disowned my mother when she married my father.  They were estranged until I was a teenager. It was so sad, because when my mother was a child her mother would tell her someday everyone would marry everyone else and the world would be filled with beautiful golden people.  I guess they just didn't mean for her to get things started! Anyway, being mixed was very unusual when I was a kid but it seems so normal now. When I was getting married a few people asked me what I thought about opur kids being mixed and I had no answer - I hadn't even thought about it. 

 

I think round-y faces run in Irish families too.  My boys have fantastic chunky cheeks, like my Irish dh.
