From analysis of the 12 Drosophila species genomes,
Zhang et al. (2010) identified 947 young
protein-coding genes that were created recently in the
lineage leading to D. melanogaster. We listed
D. melanogaster stocks that are assigned to 412
"very young" genes.
These "young" genes are classified as 102 retrogenes,
741 DNA-level duplicates, or 104 other newly created
protein-coding genes. We listed 412 "very young" genes
originated on branches 4 - 6 (see Figure) and stocks that are
assigned to these "very young" genes. As for insertion
stocks, we selected those that are located within 1-kb of
transcriptional region. Stock information was acquired from
Kyoto DGRC,
NIG-Fly,
and
FlyBase;
mRNA expression data come from
FlyAtlas.

genes originated on branches 0-6. For example, 68 genes were
created after divergence of D. yakuba and
D. erecta but before divergence of D. simulans
and D. sechellia (branch 5).
