Pete,  without complete geographical isolation of one honey bee breeding
population from another, there will always be gene flow between the
populations.  The designations of species or race is strictly a human
construct--with arbitrary lines being drawn.

The above said, there are also "clinal" expression of genes--as
demonstrated in the differences in morphology and behavior of a genetic
line, depending upon climate, elevation, etc.

The above applies to Charlie's observations (which I completely agree
with).  Queenlines from a breeder may exhibit different characteristics
when kept in different climates, honeyflows, or with different management
(e.g., single vs. double brood chamber, or with or without supplemental
feeding).
