What's with the identical twins?

This year on American Idol, two of the final twenty-four contestants had identical twins, and another pair of identical twins were doing well in the competition until they were ejected due to scandal. I didn't watch American Idol last year, but I understand a pair of identical twins did well last year also.

About 4 in 1000 births yield identical twins, and 12 in 1000 births yield fraternal twins, so I reckon the chance of an individual having an identical twin is about 0.8%. By random chance, American Idol should have had about one identical-twin contestant by now, but four to six?

Maybe it helps to study music with a singing partner who has a similar voice to yours.
