How do seedless grapes grow?
Seedless grapes are a special bunch.
All plants -- including grapes -- grow from seeds. But some people prefer to munch on sweet, juicy grapes without biting on seeds too. So, grape breeders (those are people who develop different kinds of grapes) use their plant smarts to grow the seedless varieties.
Grape breeders create new seedless plants by placing the pollen of a seedless grape onto the flowers of a grape variety that has seeds. They then cut open and inspect the fruit of every single plant that grows from this match. The breeders are looking for seeds -- some plants will have seeds in their fruit and others won't.
When they find a plant that has no seeds, or maybe just has very tiny traces of seeds that you wouldn't be able to taste, the grape breeders use it to make more seedless plants. One way is to cut off small pieces of the seedless plant's vine and place it in special growing conditions in a greenhouse. Eventually, the pieces of vine will grow roots and become new, individual plants. This technique is called propagation.
Or, the breeders can graft, or attach, a piece of the seedless grape variety onto a healthy vine base, called a rootstock. Think of it like this: When someone cuts their hand, a doctor sews the cut together, and the two pieces heal as one. The grafted vines grow together the same way. And, the grape variety attached to the rootstock keeps producing delicious seedless grapes.

Same way all seedless fruits are grown. You take a cutting of a plant that for some reason didn't produce any seeds (genetic defect), and then you graft that branch onto the stem of a regular version of the fruit tree or bush. It will grow and produce the same seeless fruit as it did before.
To give you an example, most seedless oranges used in the United States came from the same plant, which was then grafted onto other plants to let them grow.

Devine intervention. You made a Funny pun ! :-)
Seedless grapes are cross-breed/hybridized to be seedless.
Also, seedless grapes have been available long before genetic engineering.
The way more seedless grapes are grown is by taking clippings/cuttings from the vines and propogating the clippings/cuttings.
That is the de-Vine intervention.

They're NOT genetically modified - whoever said that is a fine example of someone talking about GM when they know nothing about it, it's amazing how many people do that.
Most likely they are an F1 strain - the sterile results of a cross of two other types of grape. There are lots of plants like this, especially garden flowers.

They actually grow from cuttings from other seedless grape plants and not from seeds.

Do you remember the word "grafting" ?
They found a graft that produce a seedless....
They took "Cuttings" and grafted them.
Presto...
supply the nurseries.
but of course there is still the alien invasion and DNA alteration... :~)

i read somewhere that they treat the plants or seeds with a type of radiation, (not a level dangerous to humans), making then infertile, therefore seedless.

good observation and great that you've asked, don't know why the attitude but know you're getting answers.
Seedless grapes are a hybrid and therefore have to be grown from the grafting of vines.
