Hi Dee & all

The difference in mating preferences appears to be size related and race
related.
If you look at...
http://www.dave-cushman.net/bee/sizematingpreference.html
"Drones mating with the smaller OD models had significantly lower
thorax mass than those mating with the larger OD models"
Would indicate that small queens attract small drones, but (in another
part of the document) that drones of all sizes are attracted to queens
with large bore sting chambers.
The end result of this is that small drones will mate with more or less
any size of queen, whereas larger drones are less likely to mate with
small queens.
If we have a situation whereby AHB are small and EHB are larger the AHB
genes should proliferate at the expense of the European bee genes.
The way I read it the AHB will gain in influence as the percentage
shifts to favour the propagation of genes from small drones (which are
in the main AHB)
There are other issues about mating preference in cross race matings
whereby some preference is shown for drones of similar race, but I think
this feature is also represented more strongly in AHB and so European
bees seems doomed in the extreme long term to be overwhelmed as the
process is progressive.
