molecular phylogeny and genome evolution in the drosophila virilis species group: duplications of the alcohol dehydrogenase gene. | drosophila virilis is a prominent reference species for comparison with drosophila melanogaster in regard to patterns and mechanisms of molecular and genomic evolution. sequences were determined for 11 adh genes from 8 species of the d. virilis species group, including species from both the virilis phylad and the montana subphylad. the genome of d. virilis contains a 6-kb duplication that includes the entire adh coding region. the pattern of sequence identity within the duplication strongly sugg ... | 1996 | 8583887 |
