At the B.C. meeting, I heard an illustrated presentation by a scientist from
France, and from what I gathered, the mixing of genes between nearby
apiaries with difference genetics is not as we would expect.

I arrived late, and was at the back of the room, but, from what I could
understand of the rather technical discussion, illustrated by faint slides
with small type, the mixing between yards was *much* less than one would
expect.

Moreover, not all strains of bees interbreed well, and if they do, not all
crosses are stable.  Like oil and water, or gravel and sand in a stream,
differing strains may re-separate over time, due to differing habits,
adaptations, viabiliites, and deliberate selection within a hive through
preference shown by workers for some (related?) eggs or queens over others,
and other mechanisms.
