Population 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: 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 کاملChromosomal Inversion Polymorphism in Natural Populations of Drosophila ruberrima
Shu Fang, Fei-Jann Lin and Hwei-yu Chang (1998) Chromosomal inversion polymorphism in natural populations of Drosophila ruberrima. Zoological Studies 37(4): 309-321. The standard map of the giant polytene chromosome of Drosophila ruberrima, one of the members of the immigrans species subgroup of the immigrans species group, is constructed according to the primitive gene arrangement or standard ...
متن کاملMale recombination in Brazilian populations of Drosophila ananassae.
With few exceptions, spontaneous crossing over does not normally occur in male Drosophila. Drosophila ananassae males show considerable amounts of crossing over. In wild males of D. ananassae from Asian (2008) and Brazilian populations (1986 and 2007) variable frequencies of meiotic crossing over, estimated from chiasmata counts, suggested the existence of factors controlling male crossing over...
متن کاملInversion Polymorphism in Populations of Drosophila Subobscura from Urban and Non-urban Environments
Populations of Drosophila subobscura from the urban area of Belgrade and from the locality, Deliblato, which is not under strong anthropogenic influence, were studied with the aim to characterize and compare their genetic structure by examining chromosomal inversion polymorphism. Additional analysis and comparison of this type of polymorphism with several other populations from different habita...
