Table 1

Expected and observed ratios between the chromosome 4 and 10 derived signal intensities after correction for the background. The first row shows the same subjects as figs 1-3. The second row lists the different repeat array constitutions as inferred from PFGE (fig 1B). The third row indicates the expected 4:10 ratios while the fourth row shows the 4:10 ratios obtained by the BglII-BlnI dosage test
