Hasselmann and Beye, 10.1073/pnas.0307147101: Martin Hasselmann and Martin Beye from the Martin-Luther University in Halle, Germany analyzed the sequence differences within and between honey bee populations of the sex determining locus csd (complementary sex determiner). With their findings they imply a new understanding of both the function of the multiallelic mechanism and the adaptive processes on the level of nucleotide sequences. In addition, with their first csd sequence data they believe now to have a notable basis for the avoidance of diploid males in bee selection programs by "allele-assisted breeding." This certainly will be of economic interest for bee keepers.
