Daniel Weaver admits having some scutellata genes in his bees. So I guess Weavers are somewhat Africanized. However as he explains, it's not necessarily a bad thing.
I did notice that some of the traits he found among resistant bees are similar to mine, primarily the small population in winter. However, in my case at least, the ones that survive the winter and go on to prove they can year after year are very frugal with their stores. I have not experienced late build up or increased defensiveness in my own bees, though some that I purchased have been a little hot.
