In maize, the O2 gene, located on chromosome 7, controls the texture of the endosperm, and the C gene, located on chromosome 9, controls its color. The gene on chromosome 7 has two alleles, a recessive, o2, which causes the endosperm to be soft, and a dominant, O2, which causes it to be hard. The gene on chromosome 9 also has two alleles, a recessive, c, which allows the endosperm to be colored, and a dominant, C^I, which inhibits coloration. In one homozygous C^I strain, a Ds element is inserted on chromosome 9 between the C gene and the centromere. This element can be activated by introducing an Ac element by appropriate crosses. Activation of Ds causes the C^I allele to be lost by chromosome breakage. In C^I/c/c kernels, such loss produces patches of colored tissue in an otherwise colorless background. A geneticist crosses a strain with the genotype o2/o2; C^I Ds/C^I Ds to a strain with the genotype O2/o2; c/c. The latter strain also carries an Ac element somewhere in the genome. Among the offspring, only those with hard endosperm show patches of colored tissue. What does this tell you about the location of the Ac element in the O2/o2; c/c strain?
