Abstract
This article discusses the major differences which can be fuond from time to time in homozygotic twins. In some instances there may be differences in manifestation, as in the case of a pair of monozygotic twins, aged 12, with concordant dysplasia of the hipjoint but with different radiological pictures. Differences may also be due to particular incidents during intrauterine life, alterations in growth resulting from hormonal disturbances etc. In some cases the cause of the differences is not known and, as an example, the author cites a monozygotic twin-pair aged 10, one member of which is much retarded in growth while the co-twin suffers from coloboma of the iris.
