Red Headed!!

Redheadedness is a recessive gene: a genetic mutation. This means red hair only occurs when two people carrying that same recessive gene marker, have children who also inherit that same recessive gene. Who pass it onto their children. And so on. Ad infinitem.

The recessive gene for red hair was discovered in 1995-1997 by Edinburgh University Professor, Dr. Jonathan Rees, who conducted a study on redheads and identified the single gene responsible for red hair: melanocortin 1 receptor (MC1R), on the 16th chromosome.
