| nonfixed duplication containing the adh gene and a truncated form of the adhr gene in the drosophila funebris species group: different modes of evolution of adh relative to adhr in drosophila. | the sequence of the genomic region that contains the adh and adhr genes of drosophila funebris was used to demonstrate that both genes are present in species of the funebris group. the sequence of this genomic region reveals a 2.9-kb tandem duplication which encompasses 1.6 kb of the 5' flanking region, the entire adh gene, and two thirds of the first exon of the adhr gene in d. funebris. this duplication is not fixed in this species since some strains do not carry the duplication. the adh dupli ... | 1999 | 10555275 |
