This is too general a statement to be useful...
Each of the races has a range of cell sizes that it can use or
accommodate to. Each range is represented by a 'normal distribution'
bell shaped curve. The curves for each racial type overlap considerably.
This is further complicated by the curve for AMM being of greater range
than the others, to the extent that it almost encompasses the curves of
the other races.
The centres of the curves are represented in the Eva crane cell size
figures that can be found in Bee-L archives under the subject heading
'Cellsize...More Information' message 033035.
One of my gripes about the usefulness of FABIS is that the upper range
for AHB overlaps considerably with Ligustica and the lower portion of AMM.
Now on top of this comes the conjecture...
I am of the opinion that the wide range exhibited by AMM is actually
caused by two subsets of genes that perhaps ought to be considered as
different sub races. I have no proof, all I have is an ever growing
suspicion based on two types in each category of behaviour being found
among stocks that are already well documented as to pedigree.
Similar to the authors of...
Phylogeographical autocorrelation of phenotypic evolution in honey bees
(Apis mellifera L.)
I am of the opinion that we will find out a lot more about this subject
over the next few years, I am not worried whether I am right or wrong,
but I would like more concrete answers than we have at the moment.
