High resolution pattern of an inverted duplication (15).
The nature and the origin of a supernumerary marker chromosome in a mentally retarded boy were determined by various staining techniques on metaphase chromosomes and by GBG high resolution technique. The karyotype was found to be 47,XY, + inv dup(15) (pter----q13: :q13----pter) and the supernumerary chromosome was of maternal origin.
