Abstract:
A sample of 122 twin pairs and 166 singletons from the urban Punjabi population of Chandigarh was studied. The observed frequency of double occipital hair whorls was higher in twins than in singletons (P less than 0.01). The possible association between twinning and double occipital hair whorls is discussed.
