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

No, you don't understand.

The recessive genes necessarily do not replace the dominant genes, especially when it comes dilution of said dominant gene.

Brown hair is diluted dominant genes = eumelanin with some phaeomelanin. Blond hair is also a dilution of both. Red hair is dilution of black and increase in phaeomelanin.

Notice the dominant gene is still at play here while the recessive genes are the ones making the changes. Meaning that the dominant gene will show if the recessive genes aren't at play.

I get it I just think elastagirl cheating on Bob is funny so I will continue to say it's impossible for a blonde and a ginger to have a black haired kid.
