Eye ColorEye color comes in three inherited looks - brown, green, and blue - plus an unnatural set that's character-creator only. Brown is dominant and blue is recessive, which makes blue the rarest to inherit.4
Face FrecklesFreckles are a single on-or-off trait. Having freckles is dominant - one parent passing them on is enough - so freckle-free children need both parents to lack them.2
Hair ColorHair color is inherited as black, brown, or blond. Black is dominant and blond is recessive, so two dark-haired parents can still have a blond child if both carry the gene.4
Hair TextureHair texture runs from straight to coily. Coily and curly are dominant over wavy and straight, so straight hair only appears when a child inherits it from both parents.4
Skin ColorSkin tone isn't a short list of looks. It's set by an undertone family and a lightness level from 0 to 6, and a child blends toward a tone that sits between their two parents.42
