Family reunion is the next area being delved into by the reality genre.

US network FOX has announced plans for an "extraordinary" special which will see a girl, adopted at birth, attempting to pick out her biological father from eight paternal candidates.

Who's Your Daddy?, due to air January 3, will feature an obligatory twist: $100,000 will be hers if she guesses right. If she makes the wrong choice, the imposter walks away with the money.

FOX has been particularly bold with pioneering new reality shows in recent years. Former controversies include The Littlest Groom, a dating show for dwarves; Man versus Beast, a series of Olympic-style events between men and animals; and Married By America, an interactive show which saw viewers play cupid and pick out two singles to wed.
