>>We were all very excited that our Striped Okeetees retained black in their patterns...Usually the striped gene takes most, if not all, the black out... but ours show defined black striping...
Yeah, Graham's correct. Many cornsnakes have been called striped Okeetee cornsnakes for years because they were red and orange. ...NOT because of the black stripe. It was always believed that the striped (and motley) mutation REMOVES the heavy black striping. We've got the striped Okeetees with heavy black stripes that are almost an entire scale row wide. Not bad at all. A good frined that is LARGE into cornsnakes for a living laughed and said we were wasting our time.....and then tried to buy an extra male from us.....lol. We gave it to him, but that just shows how surprising this line is....and how unsurprising most other lines are.
So, the motto? Check an image. It is possible it is a striped okeetee with black, but it is unlikely to have much black. Only an image can tell, and you get what you pay for. 
Like Graham said, we are in the process of improving this line by breeding it to some of the best "Improved Abbott's," or extreme, Okeetees to bring out the black even more while taking the orange/red color combo up a notch. Graham doesn't know it yet, but I'm also going to bring these into a high white reverse Okeetee line to try and get a striped albino corn with wide white lines down the back. 
Oh, I'm just babbling. That project will start this year, but it'll be 2-3 more years before we see marked improvements from our projects. Fingers crossed, and isn't selective breeding fun?
