The correct answer is: Turner's syndrome
Barr body is a rod-like structure visible in the somatic cells of females. Since females have two X chromosomes, only one is functional and the other undergoes coiling to form a rod-shaped structure during interphase, known as Barr body. Turner's syndrome is female has only one X chromosome thus Barr body is absent.
