Courtship behavior and control of reproductive isolation in Drosophila mojavensis: genetic analysis of population hybrids.
Drosophila mojavensis from the Sonora region and Baja California show asymmetrical sexual isolation in the laboratory: males from Sonora mate equally frequently with Sonora and Baja females, while the mating success of Baja males with Sonora females is reduced. This failure has been localized to three separate behavioral landmarks occurring during courtship. Genetic analysis was conducted using...
متن کاملP-4: Grape Seed Extract Alleviate Male Reproductive Toxicity Caused by Busulfan in Rat Model
Background: The alkylating agent busulfan adversely affects spermatogenesis in mammals and Impairment of spermatogenesis has been identified as an inevitable side effect of cancer treatment druges then the aim of this study was to investigate the possible protective effects of Grape seed extract with potent antioxidant activity, on busulfan-treated adult male mice. Materials and Methods: In thi...
متن کاملAssortative mating and persistent reproductive isolation in hybrids.
The emergence of new species is driven by the establishment of mechanisms that limit gene flow between populations. A major challenge is reconciling the theoretical and empirical importance of assortative mating in speciation with the ease with which it can fail. Swordtail fish have an evolutionary history of hybridization and fragile prezygotic isolating mechanisms. Hybridization between two s...
متن کاملGut microbiomes and reproductive isolation in Drosophila.
Experimental studies of the evolution of reproductive isolation (RI) in real time are a powerful way in which to reveal fundamental, early processes that initiate divergence. In a classic speciation experiment, populations of Drosophila pseudoobscura were subjected to divergent dietary selection and evolved significant positive assortative mating by diet. More recently, a direct role for the gu...
