Ok - they are hybrids, with each and every new generation (and that is quick turnaround), they pick the ones with lowest seed count, from next generation the same and same from next - see the pattern? And when they cannot find the seeds anymore, it's seedless. It's like when you try to grow the hottest peppers - with each turnaround you pick the hottest ones to plant for the next time.
Now, seriously - there are thousands of illegal workers in each fruit warehouse, pulling all nighters to pick the seeds out. Yea, from grapes too, with tweezers. Then they superglue them back . . . .
