Hair genetics

[JisthenewK]

My mum has naturally brown hair, so does my dad. Her hair was actually blonde when she was younger. In her teen years, her hair naturally became darker until it was brown. Anyway, my brother is a redhead and I am a natural blond (brunette, now that I dyed it). So if anyone knows how to explain my mum and dad both being brunette and having two kids of different hair colours, please tell me why.

I wouldn't worry too much about it.
I have auburn hair , my sister has black hair yet my nephew has red hair and his father also had black hair.
Both my sons have dark hair ,Jays beard throws red.

It can be a throw-back to previous generations.

both of my parents hair is black but when my dad was young his hair was a dark brown. my little sisters hair is dark brown and when I was a child I had brown curly hair with blond tips but my hair is now black.
