Many of us have blond, brown or black hair, yet there is a reddish undertone especially visible when the sun is shining. There also is a unique phenomenon of having different colors of hair on different parts of the face and body. This is especially frequent in Rh(D) negative men where sometimes mustache and different parts of the beard have different colors, often different from the top of the head and the sides.

Why are Rh(D) negatives more likely to show genotypes in phenotype (appearance)?

Examples:

Reddish undertones in hair.

Hazel eyes.

Central heterochromia.
