Deafening silence about the maud bees. Someone must know something.

GG. From the Jensen paper P102.
The analysis failed to detect a clear phylogeographical pattern of
the Scandinavian, British, Belgian and French populations
of A. m. mellifera, irrespective of whether introgression
of A and C-haplotypes was taken into account (Fig. 5a)
or not (Fig. 5b). This is because the extant A. m. mellifera
populations mostly have the same spectrum of haplotypes,
consistent with a fairly recent common ancestry (Garnery
et al. 1998a).
ie, if the common ancestry is recent you would not easily be able to distinguish one AMM population from another.
