The alpha-globin genes of five black Americans, two Chinese, and five
Filipinos with HbH disease (an alpha-thalassemia state in which there is a
single functional alpha gene) were analyzed by restriction endonuclease
techniques. All subjects were found to have one chromosome 16, lacking both
alpha genes, and another containing a single alpha gene (--/-alpha).
Restriction endonuclease patterns of the DNA obtained from all 12 subjects
were identical and compatible with unequal crossing-over as the mechanism
of origin of the single alpha gene in these individuals.
