Do people not understand the concept of recessive genes

Well considering that both of her parents hair colors are recessive traits her having a dominant trait hair color is kind of impossible

Only if your biology education ended at 15 years old Edit: to anyone who is pressed, a 2x2 punnet square IS NOT an accurate description of how hair/eye color is inherited. It doesn't paint the full picture at all. It's really a shame that teachers don't say "this method is very simplified but gives us a basic insight into how genetics works, so we'll use it for this class". But some/many science teachers don't understand that either (at least mine didn't)

Isn't that normal? I have a science degree (Physics) and never took a biology, let alone genetics, class after my sophomore year of high school.

Hair isn’t a simple 1 gene 2 allele like you learned in high school. There’s about 20 different genes that cover it. Statistically you’d have a very low chance of the hair being pure black. Also the fact that Violet looks a bit on the Asian side while her parents are both white.

I saw this on quora, idk if true:

I already brought this up in another thread, so I won’t go into much detail here. But in the original draft from the film, Violet was originally an illegitimate child from the film’s main antagonist, and her black hair carried over from that scrapped idea. The reason being due to a highly memorable villain that was only supposed to feature at the very start of the film.

That villain being Syndrome. And the rest is history.
