Four Leaf Clover

Less than 2% of the U.S. population are redheads. Most have brown eyes, with others likely to have hazel or green shades.

Like red hair, blue eye color is a recessive trait, meaning that both parents must carry the gene for a child to be blessed with it. This makes those with red hair and blue eyes the rarest minority in the world, with only 0.02%% having both.  So, Grant is about as rare as a four-leaf clover.
