Genetic Differentiation between Geographically Distant Populations of DROSOPHILA MELANOGASTER.
We have studied allozyme variation at 26 gene loci in nine populations of Drosophila melanogaster originating on five different continents. The distant populations show significant genetic differentiation. However, only half of the loci studied have contributed to this differentiation; the other half show identical patterns in all populations. The genetic differentiation in North American, Euro...
متن کاملGenetic differentiation in geographically close populations of the water rat Nectomys squamipes (Rodentia, Sigmodontinae) from the Brazilian Atlantic Forest
We examined the genetic structure and the effects of a bottleneck in populations of the water rat Nectomys squamipes, a primary host of Schistosoma mansoni. Eight microsatellite loci were studied in 7 populations from the Sumidouro region of the Brazilian state of Rio de Janeiro. Our data, covering a four-year period during which a bottleneck occurred, revealed substantial variation (6-31 allel...
متن کاملEffect of mutation on genetic differentiation among nonequilibrium populations.
The usefulness of GST and similar measures of genetic differentiation has been questioned repeatedly because of their dependence on the amount of heterozygosity within populations, creating problems when comparing degrees of divergence at loci with different mutation rates. Although the effect of mutation on GST is expected to be small in the early phases of divergence, it is unclear for how lo...
متن کاملSelective constraint and genetic differentiation in geographically distant barley yellow dwarf virus populations.
Numerous studies have documented molecular variability in plant virus populations, but few have assessed the relative contribution of natural selection and genetic drift in generating the observed pattern of diversity. To this end, gene function, environment and phylogenetic history were examined to observe the effect on genetic diversity and population structure of the PAV and PAS species of B...
متن کاملGenetic differentiation among North Atlantic killer whale populations.
Population genetic structure of North Atlantic killer whale samples was resolved from differences in allele frequencies of 17 microsatellite loci, mtDNA control region haplotype frequencies and for a subset of samples, using complete mitogenome sequences. Three significantly differentiated populations were identified. Differentiation based on microsatellite allele frequencies was greater betwee...
