dsx genomic structure and RNAi phenotypes.

1st-of-its-kind study helps answer major question about development and evolution in males versus females. New details about the behavior of the gene called “doublesex,” or dsx have been found. ” How do animals with similar genomes – such as males and females of the same species – produce different versions of the same trait? And why do some traits, like ornamental features that attract mates, vary so widely, while others, like legs, don’t?” said Cris Ledón-Rettig, a postdoctoral researcher in the IU Bloomington College of Arts and Sciences’ Department of Biology, who led the study.

The study is significant because it’s the first to look at the effect of dsx across the whole genome...
