The degree and pattern of sexual isolation among closely related species can be utilized for predicting the direction of evolution and deriving a phylogeny. The Drosophila bipectinata species complex is a group of four morphologically very similar species, belonging to the ananassae subgroup of the melanogaster species group. Sexual isolation among the… (More)
Novel polymer latexes were prepared that can be applied in several ways for the control and study of cell behavior on surfaces. Acrylic latexes with glass transitions ranging from -30 to 100 degrees C were synthesized by dispersion polymerization in a water and alcohol solution using an amphiphilic comb copolymer as a stabilizing agent. The comb had a… (More)
Pattern of mating preference of interspecific hybrid females and phylogeny in the Drosophila bipectinata species complex.
[Singh B. N. and Banerjee P. 2015 Sex-specific asymmetry in eye development in interspecific hybrids in the Drosophila bipectinata species complex. There are a number of species pairs, especially in the genus Drosophila, which despite having acquired distinct species status, can still be hybridized. Such species can be very useful for studying hybrid… (More)
The Drosophila bipectinata species complex comprises of four very closely related species namely D. bipectinata, D. parabipectinata, D. malerkotliana and D. pseudoananassae. It was found that irrespective of the evolutionary divergence among the species, FA which is reflective of the developmental precision remains nearly same in four species. During the… (More)
The Drosophila bipectinata species complex: degree of sterility and dystrophied ovaries in interspecific hybrid females.
Making interspecific hybridizations, where possible remains an unparalleled option for studying the intricacies of speciation. In the Drosophila bipectinata species complex comprising of four species, namely D. bipectinata, D. parabipectinata, D. malerkotliana and D. pseudoananassae, interspecific hybrids can be obtained in the laboratory, thus bequeathing… (More)
