We report a genome-wide search of Y-linked genes in Drosophila pseudoobscura. All six identifiable orthologs of the D. melanogaster Y-linked genes have autosomal inheritance in D. pseudoobscura. Four orthologs were investigated in detail and proved to be Y-linked in D. guanche and D. bifasciata, which shows that less than 18 million years ago the ancestral Drosophila Y chromosome was translocated to an autosome in the D. pseudoobscura lineage. We found 15 genes and pseudogenes in the current Y of D. pseudoobscura, and none are shared with the D. melanogaster Y. Hence, the Y chromosome in the D. pseudoobscura lineage appears to have arisen de novo and is not homologous to the D. melanogaster Y.
