Everyone in my family is a redhead except for me. I don't tan, and I blister and burn in the sun. I color my hair red because it looks good. People have never seen me as a brunette, and think I am a natural redhead or blonde. Do I get dark hair from my grandmother, who is also dark-headed like me?

Answer

There are several genes that control hair color, so the unique combination of genes you obtained from your family lineage led to your dark hair. It is possible that you carry some alleles on the MC1R gene, since you come from a family with red hair, but your dark hair may be masking the red trait.
