Study finds clues to aging in 'junk' DNA Aug 19, The degeneration was already known to occur, but Prof. In contrast, although older X chromosomes show a paucity of genes expressed in male tissues, neo-X genes highly expressed in male-specific tissues undergo increased rates of protein evolution if haploid in males.

F1 fly vials will typically produce approximately 30 to 75 over the same time period. Relevant PhysicsForums posts Any studies looking for a quantum bump in human photoreceptors? Hall, Michael Rosbash and Michael W. Genetic markers are commonly used in Drosophila research, for example within balancer chromosomes or P-element inserts, and most phenotypes are easily identifiable either with the naked eye or under a microscope.
