I know that this is can be easily researched, but I'd like to see everyones ideas on just how this could happen. No seeds! That's just crazy

Donna is more right than she knows..... 
"Most fruits today do not come from seeds. They come from cuttings instead. This is true of grapes, blueberries, apples, cherries, etc. (pretty much all fruits except citrus, although scientists are working on that, too). A piece of a vine or branch is cut off, dipped in rooting hormone and then placed in moist dirt so that roots and leaves form. Because they come from cuttings, new grapevines are essentially clones of the vine they were cut from.
Seedless grapes actually do contain seeds at some point. But a genetic error prevents the seeds from forming hard outer coats like normal seeds do."

I was thinking something along the lines of them being an ancient alien race that is continually sent to Earth as a "coming of age" ritual where they sacrifice themselves for the benefit of our primitive, yet appreciative planet.
IMO, the seedless grape truly is the most noble of the fruit. What an amazing sacrifice!

The secret to seedless grapes, watermelons, oranges and anything else you may find is that of the jackass. The jackass is a cross between a horse and a mule, which isn't a very good cross. The two species are close enough to reproduce, but as biology classes will tell you, they don't do so very successfully. The result is that they are sterile. Seedless jackasses, if you will.
The same is true in the plant kingdom. If you take two similar species of fruit (whatever they may be) and cross them, they typically will not reproduce at all. If they are close enough, however, they WILL reproduce, but the offspring will be sterile. By crossing two similar green grapes that are genetically dissimilar enough you come out with one that can not have it's own children, and is thusly seedless.
In China (where I've visited, lived and worked) the priority is not on commercial preference but total yeild. As a result, they haven't bred their grapes for comfort (as we have with our dominant seedless variety) but for size. As such, the grapes are nearly the size of plums, but the seeds will break a molar if you're not paying attention.
So to answer your question (which I already did, but I want a zinger for my closing) seedless fruit is the product of human bastardization... how 'bout that?

It's not always true that these seedless fruits are just down to our efforts. Sometimes nature does it for us as in the case of the king of fruits, the banana! It is reckoned that about ten thousand years ago man stumbled upon an edible variety of banana (wild bananas are so full of seeds as to render them virtually inedible) that due to a genetic accident had 3 rather than 2 chromosomes rendering them sterile - I think the ass also has an odd number which is where its fertility problems lay too. The huge problem with this is that whilst the natural enemies of the banana (various nasty fungi) have had plenty of time to evolve nasty new ways of attacking the banana, the banana is incapable of evolving new ways of defending itself. This is getting to be so bad now that many people are starting to get worried that it might even go extinct! Perhaps the best argument for genetic manipulation...?

I know exactly how seedless grapes reproduce. It is a little known ritual, whose secret is known only by the Great Slop of deepest darkest Surrey. On a certain moonlit night in April, the Great Slop dons his gown of the purest white Do-Do feathers. He undertakes a perilous journey on his hands and knees to the darkest part of the forest, where he finds the vine of Muldove, planted it is said by King Arthur himself after a great battle. From the vine, he takes two grapes, both seedless. Upon returning to the moor, the ritual is continued by the dancing of 12 naked virgin girls around a fire made from the wood of trees fallen the previous year, and left to dry under the great cathedral of Winchester. The girls hold in their hands, ribbons of red and white, to symbolise the two sexes: red for male, white for female.
The Slop takes the grapes and puts them side by side. While chanting words from the Great Book of Prostero, the grapes suddenly spring forth seeds, which when planted, produce a vine upon which grow grapes without seeds. The ritual is performed many times until enough seeds are produced to allow the planting of a great number of seedless grapevines. The ritual is only performed, however, when the number of seedless grapevines becomes in danger of failing to produce enough fruit.
Or the vines could be sprayed with a DNA substance that stops the seeds from forming. Which is the more believable explanation?
