Tom,
As a keen student I am sure you will have access to Mesquida's Elements of
genetics with special reference to the bee. If not, it is obtainable from
BIBBA. He has a little to say about linkage but unfortunately his examples
are from mice and fruit flies.
I think you are not likely to find sex linkage a productive way to select
genes to improve your stock in the short term. Try keeping at least twice as
many hives as you need and select by culling the worst queens (in terms of
genes exhibited) and uniting their hives to the best. That way you not only
improve your quality through selection but if you get the timing right you
boost the honey crop of the remainder.
