Hi Aaron

 > Is it a significant percentage or negligible?

There was quite a discussion on this on this list back in April...

Under the Thread 'Laying workers, you don't want them'

The diploid eggs laid by thelytokious bees are formed from haploid eggs 
that have a modified division process in the early stages of cell 
division, the workers that laid them have only partial ovary development 
and cannot get mated in the way a queen does.

While Thelytoky is exhibited strongly in Capensis, it does occur in all 
races of Apis Mellifera, but in all except Capensis, it is very rare.

At Capensis levels it is destructive, but at levels of one in a million 
it is unlikely to do much harm and on the rare occasion that the gene 
pool is impoverished, it can maintain genes that might be otherwise lost.
