Phylogeny of the Oriental Drosophila melanogaster species group: a multilocus reconstruction.
The melanogaster species group of Drosophila (subgenus Sophophora) has long been a favored model for evolutionary studies because of its morphological and ecological diversity and wide geographic distribution. However, phylogenetic relationships among species and subgroups within this lineage are not well understood. We reconstructed the phylogeny of 17 species representing 7 "oriental" species...
متن کاملA microsatellite-based multilocus phylogeny of the Drosophila melanogaster species complex
Uncovering the genealogy of closely related species remains a major challenge for phylogenetic reconstruction. It is unlikely that the phylogeny of a single gene will represent the phylogeny of a species as a whole [1], but DNA sequence data across a large number of loci can be combined in order to obtain a consensus tree [2]. Long sequences are needed, however, to minimize the effect of (infre...
متن کاملMating Asymmetries and Phylogeny in the Drosophila melanogaster Species Complex
The propensities for interspecific courtship and mating among the four species of the Drosophila melanogaster species complex were studied to examine Kaneshiro's hypothesis relating asymmetrical interspecific mating to the direction of phylogeny. Strong asymmetries were revealed, especially involving the ability of sechellia and mauritiana males to inseminate simulans females. A possible basis ...
متن کاملPrinciples of Genome Evolution in the Drosophila melanogaster Species Group
That closely related species often differ by chromosomal inversions was discovered by Sturtevant and Plunkett in 1926. Our knowledge of how these inversions originate is still very limited, although a prevailing view is that they are facilitated by ectopic recombination events between inverted repetitive sequences. The availability of genome sequences of related species now allows us to study i...
متن کاملPhylogenetic incongruence in the Drosophila melanogaster species group.
Drosophila melanogaster and its close relatives are used extensively in comparative biology. Despite the importance of phylogenetic information for such studies, relationships between some melanogaster species group members are unclear due to conflicting phylogenetic signals at different loci. In this study, we use twelve nuclear loci (eleven coding and one non-coding) to assess the degree of p...
