Behavioral genetics of Drosophila ananassae.
Drosophila ananassae has a unique status among Drosophila species because of certain peculiarities in its genetic behavior. The most unusual feature of this species is its relatively high frequency of spontaneous male recombination. The results of studies on non-sexual behavior, such as phototactic responses, eclosion rhythm, and preferences for oviposition and pupation sites, lead us to sugges...
متن کاملPopulation Genetics of Drosophila: Genetic Variation and Differentiation among Indian Natural Populations of Drosophila ananassae
Sanjay Kumar and Arvind Kumar Singh (2017) Genetic subdivision in natural populations of animals including Drosophila can be well understood by studying the role of evolutionary forces like natural selection, migration and genetic drift which are mainly responsible for the change in their genome. Drosophila ananassae is a cosmopolitan and domestic species and is one of the prevalently occurring...
متن کاملPopulation Genetics of Drosophila ananassae: Evidence for Population Sub-Structuring at the Level of Inversion Polymorphism in Indian Natural Populations
Drosophila ananassae is a cosmopolitan and domestic species distributed in the tropical, subtropical and mildly temperate regions. Population structure analysis in forty-five Indian natural populations of D. ananassae was performed employing three cosmopolitan inversions as markers. Pairwise FST analysis and genetic distance (D) values showed strong genetic differentiation. Though, lowermost va...
متن کاملPopulation Genetics of Drosophila Amylase
Morph frequencies of three related polymorphisms were determined in ten natural populations of Drosophila pseudoobscura. They are the well-known inversion polymorphism of the third chromosome and the polymorphism for a-amylase produced by the structural gene A m y (which resides on the third chromosome). The third polymorphism was for tissue-specific expression of A m y in adult midguts; a tota...
متن کاملGenetics of phototactic behavior in Drosophila ananassae, a member of the melanogaster species group.
Using Hirsch-Hadler photo taxis mazes, selection for photopositive and pho-tonegative behavior was carried out for 21 generations in Drosophila ananassae. The chromosomes that are important in influencing photomaze behavior in D. ananassae are different from what has been observed for other members of the melanogaster species group, and the differences cannot be entirely attributed to the chrom...
