waxy Hard smooth opaque kernel; amylopectin starch in kernel and pollen (stains red with iodine) replaces amylose flinty starch (stains blue).
waxy waxy endosperm: backcross ear segregating for opaque waxy kernels; cut surfaces stained with I2-KI (potassium iodide reajent) showing opaque red (waxy) vs. transluscent blue (non-waxy) stained kernels. Actually the photo representation of red and blue in this image is poor with red being seen as grey and blue as nearly black.

----
waxy waxy pollen: pollen grains segregating for wx1 showing differential tan (waxy) vs. purple nonwaxy pollen grains stained with I2-KI.

----
waxy 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; phenotypes of seven genes clearly displayed all on one ear!

----
waxy amylose extender-waxy; interaction: Selfed homozygous waxy, heterozygous ae1, showing translucent double ae1 wx1 homozygotes.
