1. There is plenty of genetic diversity (aka hetrozygosity). The most credible evidence suggests that Colony Collapse Syndrome was caused by a disease, not GMO seed. Also, all of the seed companies take tremendous care to ensure that their patented biotech traits (BT) keep working in future, which is why they all have refuge requirements (meaning a farmer must plant at least X percent of their crop that isn't BT, which makes sure that various pests continue to breed with genes that will make their offspring susceptible to herbicide/pesticide treatment).
2. Corn has tens of thousands if not hundreds of thousands of genes and has roughly 22 million nucleotide base pairs. Having two breeders from two different companies come up with roughly the same plant interdependently is in the astronomical range.
