red aleurone Outcross ear with purple anthocyanin, segregating for red color (pr1). Changes purple aleurone to red; flavonoid 3'-hydroxylase.

red aleurone multi-gene interaction: Selfed ear segregating for multiple aleurone and endosperm genes: pr1 (red/purple), R1 (solid anthocyanin/mottled/colorless), su1 (sugary/normal), y1 (white/yellow endosperm), sh1 (shrunken/normal kernel), and wx1 (waxy/normal), in an intense, in1, purple popcorn background. A demonstration of gene dosage, gene interaction, independent assortment, and linkage; Seven genes clearly displayed all on one ear!
