Eli5 : Why do some genes (like skin color) mix and shade upon inheritance while some don’t (like eye color) ?

We simplify gene expression pretty significant in biology using Punnet squares. It’s almost never one specific gene that’s required for traits to appear the way they do. One gene dictates the amount of melanin in your iris, but the shape and other factors also matter for determining colour.

For people saying eye colors mix – yes and no. Blue eyes are a genetic mutation and both parents need to have this trait (in their DNA) for it to be passed down or else it won’t. Same with red hair. From what I understand , there’s no passing down any kind of genetic mutation (blue eyes, or red hair) if one parent absolutely doesn’t have the genes for it

In middle school biology you would have learned about dominant and recessive traits. Dominant traits take priority over recessive traits.
In high school biology, there’s also “codominant” traits, ones that don’t take precedence. Those are the traits that mix.
