Genetics on the Fly: A Primer on the Drosophila Model System.

abstract：:Hybrid sterility is a common form of reproductive isolation between nascent species. Although hybrid sterility is routinely documented and genetically dissected in speciation studies, its developmental basis is rarely examined, especially in generations beyond the F1 generation. To identify phenotypic and genetic dete...

Our laboratory previously demonstrated that maternally deposited, long, noncoding, template RNAs are essential for programmed genome rearrangements in the ciliate Oxytricha trifallax. Here we show...
