| male accessory gland secretory protein polymorphism in natural populations of drosophila nasuta nasuta and drosophila sulfurigaster neonasuta. | male accessory gland secretory protein polymorphism was analysed in natural populations of drosophila nasuta nasuta and d. sulfurigaster neonasuta for the first time, using sds-page to score polymorphism of these proteins in 2788 individuals of d. n. nasuta and 2232 individuals of d. s. neonasuta from 12 different populations from southern india. a total of 25 and 18 variant protein phenotypes were identified in d. n. nasuta and d. s. neonasuta, respectively. protein fractions of group iii were ... | 2007 | 18305341 |
| chromosomal analysis and phylogenetic relationships in the drosophila nasuta subgroup. i. phylogenetic relationships within the drosophila sulfurigaster species complex. | phylogenetic relationships within the drosophila sulfurigaster species-complex, which belongs to the d. nasuta subgroup, were investigated on the basis of chromosomal constitution and morphology. d. pulaua is thought to be the most ancestral species, from which d. s. sulfurigaster and d. s. bilimbata derived in one branch and d. s. albostrigata and d. s. neonasuta in another branch. | 1990 | 2323566 |
| inversion polymorphism and linkage disequilibrium in drosophila sulfurigaster neonasuta. | three paracentric inversions constitute the polymorphic system in drosophila sulfurigaster neonasuta. of these, two linked inversions, namely 2la and 2ra, exhibit linkage disequilibrium, and the overall pattern of polymorphism is flexible. | 2009 | 2614063 |
| mitochondrial dna polymorphisms in the two subspecies of drosophila sulfurigaster: relationship between geographic structure of population and nucleotide diversity. | recent empirical and theoretical studies on mitochondrial dna (mtdna) variation in higher animals have suggested that the extent of mtdna polymorphism is largely affected by spatial population subdivision. to examine this we studied mtdna polymorphism in two subspecies of drosophila sulfurigaster: d. s. albostrigata and d. s. bilimbata. drosophila sulfurigaster albostrigata is mainly distributed on the mainland of southeast asia. in contrast, d. s. bilimbata forms discontinuous populations on ma ... | 1991 | 1672225 |
