My hair is a combo of both parents:
fineness, coloring( brown, sandiness/red tones), patterns of texture throughout my head from my mother(a very soft, fine/thin 3/4 mix I maybe)
fineness & thickness, dense, definitely from daddy's side (soft, thicker, frizzy wavy 3)
My hair is dominated by my dad's side overall. I have quite a few relatives on his side with identical hair to mine.
