Whole-Genome Resequencing of Experimental Populations Reveals Polygenic Basis of Egg-Size Variation in Drosophila melanogaster
Complete genome resequencing of populations holds great promise in deconstructing complex polygenic traits to elucidate molecular and developmental mechanisms of adaptation. Egg size is a classic adaptive trait in insects, birds, and other taxa, but its highly polygenic architecture has prevented high-resolution genetic analysis. We used replicated experimental evolution in Drosophila melanogas...
متن کاملLow evolutionary potential for egg-to-adult viability in Drosophila melanogaster at high temperatures.
To cope with the increasing and less-predictable temperature forecasts under climate change, many terrestrial ectotherms will have to migrate or rely on adaptation through plastic or evolutionary means. Studies suggest that some ectotherms have a limited potential to change their upper thermal limits via evolutionary shifts, but research has mostly focused on adult life stages under laboratory ...

Egg Viability, Mating Frequency and Male Mating Ability Evolve in Populations of Drosophila melanogaster Selected for Resistance to Cold Shock
BACKGROUND Ability to resist temperature shock is an important component of fitness of insects and other ectotherms. Increased resistance to temperature shock is known to affect life-history traits. Temperature shock is also known to affect reproductive traits such as mating ability and viability of gametes. Therefore selection for increased temperature shock resistance can affect the evolution...
متن کاملMicrosatellite variation in North American populations of Drosophila melanogaster.
Computer database searching for microsatellites can be particularly effective for organisms like Drosophila melanogaster for which there are extensive sequence data. Here we demonstrate that 17 out of 18 such microsatellites are also highly polymorphic in natural populations of Drosophila, and that this variation is easily scorable with PCR followed by electrophoresis on high-resolution agarose...
