text: my gf and i just had a baby, but the kid has red hair. nobody in my family or hers has ever had red hair.? should i be concerned. now one of her ex's has red hair of the 3 natural redheads i know, not one of them had a parent with red hair.  i believe it is a recessive gene.  heres what i found  "one genetics textbook explained it this way: a person with red hair has genes for light colored hair (blond), and also possesses separate genes specifying red hair. this combination makes red hair -- redheads are blonds in disguise!someone with dark hair might also have the red hair genes, but their dark hair genes overrule the red genes and so they don't have red hair. this would also explain why dark-haired parents can sometimes have redhead children."  i also don't know many true redheads that have redheaded children.  just an fyi  let it go...love your wife and your child!
