A versatile new CRISPR/Cas9 genome editing strategy allows mutation, tagging, and gene deletion in C. elegans without the use of co-integrated markers or long homology arms, report Paix et al. in an article published Early Online in GENETICS. The strategy can be easily scaled up, and should allow systematic construction of precise ORF deletions and…

In 1979, as the US slid into recession, researchers began systematically crossing eight distinct inbred rat strains. Their goal was to establish a genetically diverse rat colony to serve as a base for phenotype measurements and artificial selection. But the creators of the NIH rat Heterogeneous Stocks (HS) faced major challenges: “…the main one being…

In Stellenbosch, South Africa, in the shade of the university botanical gardens, Adam Wilkins and Richard Wrangham drank coffee and worked their way through a list. Tameness. Smaller muzzles. Smaller teeth. Patches of white fur. Floppy ears. In early 2011, Wilkins, Perspectives editor at GENETICS, and Wrangham, primatologist at Harvard, were both spending the semester…

One feverish night, just over 100 years ago, an undergraduate in Thomas Hunt Morgan’s lab created the first genetic map. Realizing that the frequency of crossing over could be used to work out out the linear order of genes on a chromosome, that student, Alfred Sturtevant, published his map in 1913 and laid the foundation…

Y chromosomes have come and gone many times during evolutionary history. Take beetles. When Heath Blackmon and Jeff Demuth modeled sex chromosome evolution in more than a thousand beetle species, they found the Y chromosome had independently evolved around 65 times in the suborder Adephaga alone. And as fast as this group evolved new Y chromosomes,…

For genome-wide association studies, data is power. The more data you have, the more statistical power you wield to find genetic associations. But are there ways to get more from the data you already have? In the May issue of GENETICS, Kaufman and Rosset describe a testing framework that substantially boosts the power of genome-wide…

The GSA Journals, GENETICS and G3: Genes|Genomes|Genetics, are proud to present our annual Spotlight booklets for research published in 2013. Each Spotlight is a showcase of the excellent research and scholarship published over the course of the year, along with a selection of striking images submitted by our authors.

In Eurasia, humans once had Neanderthals for neighbors. That time of co-existence seems to have left its marks in our genome; non-Africans today share more genetic variants with Neanderthals than Africans do. But does this really mean there was interbreeding between humans and the Hominids next door? Some have previously proposed an alternative explanation for that…

Do aging males make poorer quality sperm? Older mothers face a well-established risk of producing eggs with chromosome abnormalities, but it is less clear how age affects meiosis in males. In the February issue of GENETICS, Vrooman et al. investigated chromosome dynamics during spermatogenesis in mice of different ages. They found that meiotic errors increased…

Transposable elements don’t proliferate in genomes at a steady pace; they often arrive in bursts. But models of neutral TE evolution assume transposition occurs at a constant rate. That makes it harder to test, for instance, whether low TE allele frequencies in a population are due to negative selection or just a recent transposition burst.…
