    cough edit: you will also find that in return of the jedi he has brown hair meaning as he aged his hair got darker this is pretty normal in people who’s parents have brown/black hair

    C’mon man… Learn genetics. Seriously. Recessive genes can ABSOLUTELY express themselves in a child from even one parent being a carrier regardless of how the parents’ genes express. In addition, random mutations can and DO produce weird things.

      100% this. My wife and I are both white, but our daughter was born black. Crazy how those genetics work

      I’m also pretty sure he qualifies for the “started blond but turned brown” camp anyways. It’s so sun bleached in that photo lol

      Also, it’s a movie and these people are actors with no meaningful genetic relationship between them.

      I had very light blond hair as a child. Both of my parents have dark brown hair. My hair is now very dark brown.

        Yeah, I was light brown and blonde as a kid, black now, I have one son with blonde hair, one with black, My dad commented once that my blonde son looks just like I did as a kid, and my black haired son looks just like I do now. Also two blonde daughters, the oldest in her teens, her hair is darker in spots, but still some blonde. My youngest had a lot of red mixed in as well, but that’s all gone by now.

      In fact a similar thing happened in my family but my parents have darkening hair, and my siblings have minimally darkening blonde and brown hair. There is even some red mixed in somewhere.

    Bleach effect from Tatooine? You might need to check if the carpet matches the drapes - any volunteers? :-P

    I do ofc concede that there may be… alternative explanations.

      There are MANY explanations before sun bleaching. … though +1 for the Bleach reference.

    I don’t know how that works in outer space, but here on earth that would be totally normal and is called “genetics”. Might want to look that up some time.

    Luke has blue eyes. It is impossible for a blue eyed person to have anything but two blue eyed parents.

    Well, I don’t know where I picked up that bit of misinformation. The odds of a blue eyed person having two brown eyed parents is 25%.

      Its the opposite, parents with blue eyes can only pass on blue genes. But also everything we learned in school about genetics is a simplification. Theres a whole spectrum of eye color hues.

      Generally darker is seems more dominant so a good rule Is a child is unlikely to have darker features then the parents.

      You probably reversed something you learned a long time ago. It’s impossible for two blue eyed parents to have a brown eyed child unless there’s a random mutation, which I guess can happen, but is incredibly rare.

      TIL I cheated on my wife when she had… wait a second. /s

      That’s not true at all. Blue eyes needs two recessive genes where Brown eyes only need one recessive gene. So you can have parents where both have brown eyes but they both have the dominant gene for brown eyes and the recessive gene for blue eyes. Then if both recessive genes are passed on to a child they will have blue eyes.

      Of course there’s a few more complications to this as human eyes aren’t predicated on one gene, but it’s a good enough simplification.

      Eh, you’re close, just backwards - if both parents have blue eyes, the child is (more-or-less) guaranteed to have blue eyes.

      I have blue eyes, and my wife has brown eyes. Our daughter has blue eyes. We also have a son with brown eyes.

      Recessive genes work that way.

      The odds of a blue eyed person having two brown eyed parents is 25%.

      No, the odds of two heterozygous brown eyed parents having a blue-eyed child is 25%. I don’t think these statements mean the same thing.
