At the GSA Drosophila Research Conference, scientists will present evidence of many reversals of sex chromosome to autosomes in flies. They identified nine independently evolved sex chromosomes in a wider variety of fly species than had previously been examined and determined that these newly formed X-chromosomes have become dosage compensated, to balance the relative gene expression between males and females.
