[i] The number of radiation-hybrid cell-lines scoring positive on the Genebridge 4 panel is given. Cell-lines were typed using the TaqMan assay and scored by comparing the signal to that obtained from hamster DNA or a sample containing no DNA. The total number of cell-lines in the panel is 93.
[ii] Markers were considered polymorphic if heterozygotes and at least one class of homozygotes were detected in a sample of 30 individuals of Chinese descent. If only heterozygotes were detected, the marker was considered nonpolymorphic.
