Wow! The whole Baines family had brown eyes! I love Marty's slate-blue eyes! :)

Brown is the dominant color in genetics. I think Joey's eyes were brown too, but I didn't get a close enough look.

What about Ellen? She probably gets brown eyes as well. But what about hair color? Is it brown like Lorraine, Toby, and their parents? Or is it blonde like Milton, Sally, and Joey?

I don't think you ever said what Haven looked like.

I didn't know color contacts were around in the eighties, seeing as Biff had blue eyes and Griff had brown.

I said that Haven looks like Clara, so she would have brown hair and brown eyes. Harmony would have blond hair and blue-green eyes. I actually gave Marty Jr slate-blue eyes like his father, but Marlene had brown eyes. In the Haven Universe, Marlene is more like his grandmother, Lorraine - while Melody is like Jennifer. Biff must've gotten blue eyes from his mother. Although, I haven't really thought of what Jiff's eye colour was. Also, yeah, Ellen would also have brown eyes - and I imagined her with brown hair.

So Ellen having brown hair would even out the blond/brown ratio of the Baines children. I'm guessing Haven's eyes are a lighter brown like Clara and Jules. One thing I noticed with Jules and Verne's cartoon counterparts is that Jules' eyes were black while Verne's were blue-green. But in the movie, Verne's eyes were a darker brown than Jules.

As for the McFly kids, Dave takes after George more with black hair and blue eyes. But Dave had curlier hair which he most likely inherited from Lorraine. Linda takes more after Lorraine with brown hair and brown eyes, but she inherited George's straight hair and bad eyesight. Marty probably takes the most after both his parents. Marty had blue eyes and straight hair like his dad, and his brown hair most likely came from his mom.

Yeah, Michael J Fox does have the same hair colour as Lea Thompson - but I imagine William McFly looking just like Marty, but with brown eyes. I imagine Martin McFly looking just like his namesake, too. Of course, William would get his brown hair from his mother - who was also played by Lea Thompson. I imagine Arthur looking just like his son, George - and Arthur has an older sister named Alice, who looks like Lea Thompson.

Imagine if Eric Stoltz was never fired from the set. I wonder where he'd get his red hair from. I'm so glad they went with Michael J Fox.

Well, both Seamus and Maggie had red hair. William actually did look just like Marty. He was the "good-looking guy" that Marty asked about in the picture.

Yeah, it's supposed to be a joke - because Michael J Fox was the one to pose as William. I don't think Michael J Fox was a vain person, but he obviously knew that he was cute. In My Name Is Alex from Family Ties, Alex says, "I mean, if God wanted me to stay away from girls - He wouldn't've made me so cute."

Did you see the episode where Alex first met Ellen? He met her because he was dating her attractive roommate. But he fell in love with Ellen instead, which was weird because she's the opposite of him.

Yeah, I caught that one on YouTube! Alex may have been a bit shallow at first - but, underneath everything, he is a very sweet and kind person.

EDIT: Sorry. I double posted.

I didn't give Marty Jr brown eyes in my stories - even though I did give William brown eyes. Marlene does have brown eyes, as well.
