Table 1. Y-linkage across the 12 Drosophila species of genes that are Y-linked in D. melanogaster.
Unabridged species names (in the order of appearance) are: D. melanogaster, D. simulans, D. sechellia, D. erecta, D. yakuba, D. ananassae, D. pseudoobscura, D. persimilis, D. willistoni, D. mojavensis, D. virilis, and D. grimshawi. "+" Y-linked gene ; " − " autosomal or X-linked gene; "0" gene absent from the genome.

As described in ref.23 the Y chromosome became part of an autosome in the D. pseudoobscura lineage.
†
The FDY gene is a functional duplication to the Y of the autosomal gene CG11844, which happened within the D. melanogaster lineage, after the split from D. simulans (ref.21; A. B. Carvalho and A. G. Clark, in preparation).
