Twin studies
Rife (1933) looked at 13 pairs of monozygotic twins. Seven of the pairs had opposite whorls: clockwise in one twin, counterclockwise in the other. Sharma (1985) looked at the hair whorls of 27 pairs of identical twins and found one pair with opposite whorls.
Hair whorl and handedness

He also surveyed 49 non-righthanded people (this includes left-handed and ambidextrous individuals) and found that 44.9% had counterclockwise whorls.
