Abstract
Sex determination in honeybees involves a multi-allelic locus, such that homozygotes develop as males and heterozygotes as females. In this issue of Cell, report the cloning of the sex-determining gene, csd. It codes for an SR protein, and different alleles have very different amino-acid sequences. Inactivating csd leads to development as a male.
