abstract：:The sex determination pathway is different between Drosophila melanogaster and Bombyx mori in the initial signal. Here we show evidence that the sex determination pathway in B. mori is similar to that of D. melanogaster at the level of the terminal regulator, doublesex (dsx), which is essential for the proper differen...
