- Yellow endosperm coloration is dependent upon the interaction of the dominant allelomorphs of y1 and y3. Genetic tests indicate that Y3 is closely linked with al, a chlorophyll deficiency type. By means of trisomic tests both al and y3 are shown to belong in the second linkage group. The order of the genes is not indicated, but both al and y3 are near lg1.
