Evolutionary history of the Drosophila bipectinata species complex.
Groups of recently diverged species offer invaluable glimpses into the history and genetic basis of speciation and phenotypic evolution. In this report, we combine phylogenetic and population-genetic approaches to reconstruct the evolutionary history of the Drosophila bipectinata species complex. This complex is a group of four closely related, largely sympatric species--D. bipectinata, D. para...
متن کاملDrosophila bipectinata species complex.
The Drosophila bipectinata species complex belongs to the ananassae subgroup of the melanogaster species group (Genus Drosophila, Subgenus Sophophora). The members of the complex are: D. bipectinata, D. parabipectinata, D. malerkotliana, and D. pseudoananassae. Of the four species, D. bipectinata is most widely distributed. Females are indistinguishable, but males are distinguishable by their s...
متن کاملPopulation Genetical, Behavioural and Evolutionary Studies in the Drosophila bipectinata Species Complex
Comparison of population dynamics with regard to chromosomal arrangements, protein and nucleotide polymorphism among closely related species can provide invaluable glimpses into the intricacies of speciation. In addition, recently diverged closely related species may also exhibit behavioural differences especially sexual behaviour which can be compared across the species and eventually may aid ...
متن کاملMating latency, duration of copulation and fertility in four species of the Drosophila bipectinata complex.
Significant interspecific variations in mean duration of copulation and fertility were observed in four species of the Drosophila bipectinata species complex. However, D. bipectinata showed positive correlation between duration of copulation and fertility. Similarly, D. malerkotliana showed negative correlation between mating latency and duration of copulation. Likewise, D. pseudoananassae show...
متن کاملGenetic interactions underlying hybrid male sterility in the Drosophila bipectinata species complex.
Understanding genetic mechanisms underlying hybrid male sterility is one of the most challenging problems in evolutionary biology especially speciation. By using the interspecific hybridization method roles of Y chromosome, Major Hybrid Sterility (MHS) genes and cytoplasm in sterility of hybrid males have been investigated in a promising group, the Drosophila bipectinata species complex that co...
