Hello, everyone, I hope someone is interested in this. I'm trying to find out how the Louds inherited the colors of their hairs.

Let's start with Lincoln; his hair is white, which is surely the most recessive gene in the universe of the series, otherwise there would have been far more people with it. So, since Lincoln has white hair, he must have inherited it from both his mother and his father's sides. In the episode "Cover Girls" it has been confirmed that Lincoln inherited it from Albert (Pop-Pop), and we saw a flashback of Lynn Sr.'s father which has white hair and is dressed like a 1970s hippie, period during which he had Lynn Sr. (who is about 40) and so I guess he wasn't so old and, like Lincoln and Albert, he had white hair from birth. In any case, both Lynn Sr. and Rita are carriers of the white hair gene, but he also carries brown hair gene and she also carries blonde hair gene (probably from their mothers). Both brown and blonde would be dominant genes compared to the white one, and that's why they have them and not the white. Then, Lori, Leni, Lola, Lana and Lily's blonde hair would be caused by the combination of Rita's blonde gene and Lynn Sr.'s white gene, while Luna, Luan, Lynn and Lisa's brown hair would be caused by the combination of Lynn Sr.'s brown gene and Rita's white gene, making all of them heterozygous.

Has all of this been solved? Unfortunately no, we missed Lucy. We know for sure that Lynn Sr. and Rita can't carry black hair, because it is a dominant gene, and Lincoln might not have had white hair, but black, blonde or brown. I'd think Lucy dyed her hair, maybe to resemble her great-grandma Harriet. Is it possible, in your opinion? Or do you have any other theories?

Thanks in advance.
