transmission quantitatively by comparing the numbers of female reactors and male reactors observed in the random populations with the expected numbers; sex-linked recessive inheritance is distinguished from the other modes of inheritance by the fact that the expected frequency of female reactors is given by the square of the expected frequency of male reactors. The data were found to fit this hypothesis (see Table 5.12).
Many years later, the gene that encodes G6PD was shown to be located on the long arm of chromosome Xq28 between the genes for factor VIII and for color
