Regarding inbreeding and the Laidlaw and Page 1982 paper:
This good contribution has been perhaps taken too literally as a dire
warning, while disregarding the approach and assumptions outlined in
the paper. I don't have the paper available, but from what I remember,
it assumed a low number of matings per queen (with the information
available at that time) and it certainly assumed a closed population,
with no new material of any sort introduced through the years of
crosses. It was an exercise to model required numbers that gave
probabilistic results and expectations.
"We" are here now, in a very different situation. There is no one that
I know of trying to maintain an absolutely closed population (partly
because it is not possible or prohibitively expensive). More pertinent
to the original modeling, the number of estimated matings per queen
have been found to perhaps be higher by ten fold than when the paper
was produced. This changes the risk of losing alleles considerably.
Thinking that anyone attempting anything ranging from queen rearing, to
maintenance of certain "stocks", or furthermore selection and
improvement of any kind has bigger issues to contend with.
