A total of 70 karyotypes of infants from triplet pregnancies and their parents from 17 families were examined. The karyograms of 16 families showed a normal number of chromosomes and no abnormal morphology. Only in the 17th family a girl showed an additional chromosome in group G and deletion of the long arms in another from group C. A high concentration of developmental malformations was however present in this family.
