-            The selfed ear of an Ac/-, C2 Ds-4L6/c2 plant showing several unique phenotypes expressed by different combinations and dosage of Ac, C2, and Ds in the 3N endosperm and 2N maternal pericarp. The dilute kernels are C Ds/c/c, most of which have Ac, and are mosaic for colorless (C Ds/-/-, Ac/-) and show distinct small dark dots (C Ds C Ds/c/c twin spots) and a few intense dots (C Ds C Ds/C Ds C Ds/c/c, second cycle twin spots). The intermediate colored kernels (C Ds/C Ds/c), which have Ac, are dilute, mosaic and have coincidental colorless spots and intense (C Ds C Ds/C Ds C Ds/c) twin spots. The dark colored kernels which have Ac are dark with lighter small dots and occasional colorless dots from coincidental loss of all three C alleles. The other kernels, lacking Ac or with 3 doses of Ac, are simply dilute, intermediate, and full-colored. The colorless kernels are c/c/c with all combinations of Ac. The whole ear is covered by the same 2N maternal pericarp, as shown by the long red reversion streaks from the P-v allele where unstable Ac resides.  These results prove that Ds in this case is on the distal side of the c2 locus from the centromere.
