July GENETICS Highlights
Check out the July issue of GENETICS by looking at the highlights or the full table of contents! This Month’s Centennial Articles Alfred Sturtevant and George Beadle untangle inversions, pp. 1001-1003 R. Scott Hawley and Barry Ganetzky R. Scott Hawley and Barry Ganetzky introduce Sturtevant and Beadle’s 1936 Classic that explained why inversion heterozygosity in the Drosophila X…

Two-faced protein both speeds and slows cell cycle
Although some proteins have a single career, many—like Dis3—lead a double life. In the yeast Schizosaccharomyces pombe, loss-of-function mutations in dis3 cause defects in mitosis, implying that Dis3 normally supports cell cycle progression. But perplexingly, results in humans suggest that Dis3 normally slows cell cycle progression: mutations that partially disable dis3 contribute to the development…

Selfish self-fertilization hampers adaptation
When finding a mate is difficult, self-fertilization offers a tempting solution by increasing the number of offspring an individual can produce. But although “selfing” provides a stopgap solution when mates are scarce, it is frequently an evolutionary dead end; when environmental conditions change, species with high selfing rates seem prone to extinction. In an article…

Fecal alchemy: Turning poop into genomics gold
When it comes to genotyping technology, poop genetics is stuck in the 1990s. While most geneticists are now awash in genome-scale data from thousands of individuals, those who depend on fecal and other non-invasively collected samples still rely on old-school, boutique panels of a dozen or so genetic markers. But feces — along with fur,…

Fish with robot friends: linking genes to behavior
The relative contributions of nature and nurture to behavior are a perennial source of dispute. That there is a genetic component is clear, but frustratingly, only a handful of specific genes are known to directly influence behavior in vertebrates. In the June issue of GENETICS, Greenwood et al. describe how they pinned down one of…

Jamborees of GENETICS Authors
By guest authors Robert K. Herman, Gabriela Huelgas-Morales, and David Greenstein This summer, GSA is throwing a genetics shindig–The Allied Genetics Conference (TAGC)–to bring geneticists from multiple disciplines together to promote interaction and cross-fertilization among fields. In a way, this meeting extends a current trend: GENETICS authors have been aggregating for some time. Those of us…

Inbred Neanderthals left humans a genetic burden
The Neanderthal genome included harmful mutations that made the hominids around 40% less reproductively fit than modern humans, according to estimates published in the latest issue of GENETICS. Non-African humans inherited some of this genetic burden when they interbred with Neanderthals, though much of it has been lost over time. The results suggest that these harmful…

June GENETICS Highlights
Check out the June issue of GENETICS by looking at the highlights or the full table of contents! This Month’s Centennial Articles Joshua Lederberg on bacterial recombination, pp. 613–614 Mark Johnston GENETICS Editor-in-Chief Mark Johnston introduces Joshua Lederberg’s GENETICS Classic Gene recombination and linked segregations in Escherichia coli, which describes the first genetic analysis of bacteria. Lederberg’s discovery that…

How worms that pump iron get fat
Despite its reputation as an innocent essential mineral, excessive iron intake can be poisonous, and maintaining the proper amount within our cells requires a molecular balancing act among several biochemical pathways. Even at levels that are not overtly toxic, iron overload in humans has been associated with an increased risk of obesity and related conditions,…

Milking the Data: How genomic selection herded in a breeding boom
Sometimes, great advances in science come from combining the old with the new. Genomic selection is one such case; in 2001, Meuwissen, Hayes, and Goddard surveyed the changing landscape of genetics, had the foresight to work on a then-theoretical problem, and laid the foundation for a boom in biotechnology-assisted breeding that continues to this day.…

Action at a distance
While the textbook enhancer is often depicted just upstream of a gene, many enhancers influence transcription from afar—some can activate genes a million base pairs away. Enhancers can even activate genes on a completely separate chromosome (i.e., in trans), a process called transvection. It’s not known how common transvection is, but an article in the…
