Interspecific sexual isolation and phylogeny among different members of the Drosophila bipectinata species complex
The degree and pattern of sexual isolation among closely related species can be utilized for predicting the direction of evolution and deriving a phylogeny, and it is suggested that D. bipectinata and D. malerkotliana show asymmetrical sexual isolation.
The Drosophila bipectinata species complex: phylogenetic relationship among different members based on chromosomal variations
The polytene chromosomes of larvae obtained by crossing D. pseudoananassae with the other three species were very thin with gross asynapsis in all the arms, demonstrating that the genome of D. bogusanassae is widely diverged from rest of the species.
Sex-specific asymmetry in eye development in interspecific hybrids in the Drosophila bipectinata species complex
The occurrence of asymmetrical eyes in hybrid males having D. pseudoananassae as one of the parental species is described and the possible explanation(s) for such an abnormality are given.
The Drosophila bipectinata species complex: degree of sterility and dystrophied ovaries in interspecific hybrid females
The failings of the heterogametic sex, quite customary in interspecific hybridizations, have been called Haldane’s rule and it has been found that the hybrid sons are not just sterile but from certain crosses they show other abnormalities too, like poor viability and asymmetrical eyes (Singh and Banerjee 2015).
Pattern of mating preference of interspecific hybrid females and phylogeny in the Drosophila bipectinata species complex
The possibility of getting hybrids from absolute species opens new prospects for an evolutionary biologist, providing insights into how genomes of two independently diverging lines would function or interact when brought together in an individual.
Studies on fluctuating asymmetry (FA) for certain morphological traits in four species of the Drosophila bipectinata complex
Interspecific hybridization does not affect the level of fluctuating asymmetry (FA) in the Drosophila bipectinata species complex
Specific developmental pathways are more susceptible to developmental disturbances due to genomic incompatibilities than the large complex system bringing about developmental stability.
