BACKGROUND Gene-poor, degenerate Y chromosomes have evolved repeatedly from ordinary autosomes, but little is known about the processes that silence most genes on an evolving Y. RESULTS Here, I quantify relative expression levels of 58 gene pairs on the recently formed neo-sex chromosomes of Drosophila miranda, in order to test competing models of gene inactivation on its newly evolving Y chromosome (the neo-Y). Although the neo-Y of D. miranda still contains the majority of its original… CONTINUE READING
