-        Duplicate factors orp1 and orp2 give 15:1 ratio of normal vs orange color in overlaying maternal pericarp on homozygous orp1, orp2 kernels from selfed double heterozygous ear. Mutant orp kernels;  weak, narrow leaf, brownish palegreen seedlings with spots, barren nodes and odor of phenol;  roots and shoots flouresce blue under uv light and which produce sickly brownish green mutant seedlings that are morphologically altered and smell like indole.  In addition these factors provide excellent demonstration of duplicate factor behavior and linkage and altered genetic transmission in the corn plant.
+        Duplicate factors orp1 and orp2 give 15:1 ratio of normal vs orange color in overlaying maternal pericarp on homozygous orp1, orp2 kernels from selfed double heterozygous ear. Mutant orp kernels produce weak, narrow leaf, brownish palegreen seedlings with spots, barren nodes and odor of phenol. The orange pericarp duplicate factor mutants present a unique demonstration of the great amount of phenotypic variation that can occurr as the consequence of one or two genetic changes;  the production of orange pigment in the pericarp (maternal tissue) that segregate with the kernel (filial tissue) which produce germinating kernels whose roots and shoots flouresce blue under uv light and which produce sickly brownish green mutant seedlings that are morphologically altered and smell like indole.  In addition these factors provide excellent demonstration of duplicate factor behavior and linkage and altered genetic transmission in the corn plant.
