if you live in the USA, then about 85% of the corn is now GMO. But you can't really tell it by looking at it.

Concur, ther is no observable difference. I assume you mean sweet corn, so fusions percentage is way too high. Only Syngenta markets GM corn at the moment and they still do not dominate the sweet corn seed market. The modification is for Bt to control earworms. Field corn is a different story. Dekalb has a whole line of round-up ready types.

What about taste? If you buy a sample can you taste any difference in flavor or texture before loading up on some?

No, variation taste is among cultivars. Bt modification does not affect it.
