Where do you buy genetically engineered seeds for a science project?

It might be difficult to buy genetically engineered seeds for a science project. The seeds are patented, so the company that created the GM seeds holds the rights to the seeds. Monsanto is one of those companies and in the past they have not allowed their seeds to be used for experimentation without their permission. You could; however, contact Monsanto or another company that has developed GM seeds and ask them if you could buy some for your project.
