Drosophila pseudoobscura

Quick Reference

The second Drosophila species to have its genome sequenced. When the sequences of D. pseudoobscura and D. melanogaster were compared, it was observed that the vast majority of genes remained on the same chromosome arms. However, within each arm the gene order was extensively shuffled. See Chronology, 1944, Dobzhansky; 2005, Richards et al.; inversion, syntenic genes.
