What determines seed shape in corn kernels?
Kernel size (small medium or large) and shape (round or flat) is determined primarily by the position of the kernels on the ear. Seed size and shape can also vary by hybrid and weather conditions during seed production, including temperature and rainfall.
What determines the shape of popcorn?
Each kernel contains a tiny bit of water surrounded by starch. As the kernel heats up, the water vapor expands, turns into steam and heats the surrounding starch into a gooey mess. At a high enough pressure, the starch goop bursts through the shell and then cools down quickly into the fluffy popcorn shapes.
What is the size of a corn seed?
As early as 1937, Dr. Kiesselbach (University of Nebraska) compared across several years, large (29.2 g or 1.03 oz/100 seed) and small (15.8 g or 0.56 oz/100 seed) seed of open-pollinated corn.
What is the texture of corn?
Sweet corn kernels contain phytoglycogen, which provides the characteristic creamy texture. The covering or pericarp of the kernel contributes to the sense of texture. The pericarp of su and se corn is similar, while the pericarp of sh2 corn may have a crunchy texture or firmness, depending on variety.

And when these lobes expand away from each other, you get butterfly popcorn.
