DNA typing of MAMA clones. Primers found to be polymorphic in the germ line of the patient are used to genotype the hybrids. Hybrids found to be monoallelic are propagated and genotyped. Shown are three such examples from three separate patients. In each case the patient is polymorphic and each clone is monoallelic for chromosome “A” or “B.” An overexposure of the autoradiograph is made to confirm that no residual chromosomes containing the “lost” allele remain in the hybrids.
