New associate editor, Emily Clark, joins G3
A new associate editor is joining G3: Genes|Genomes|Genetics. We’re excited to welcome Emily Clark to the editorial team. Emily ClarkAssociate Editor Emily Clark is a research group leader at the Roslin Institute, University of Edinburgh, in Scotland. Her research group provides highly annotated genomes for farmed animals as resources to inform genome editing, genomic selection,…

Fowl play: the genetics of chicken sociability
A new study reveals genetic changes that affect social behavior in chickens. We have a number of phrases that relate human behavior to that of chickens; for example, when you accuse someone of acting “chicken,” you’re likely calling them a coward. If someone is running around like a chicken with their head cut off, they’re…

To make an embryo, you gotta break some mitochondrial DNA
Over twenty years ago, somatic cell nuclear transfer (SCNT) let scientists successfully clone the first mammal—Dolly the sheep. Despite advances since then, the efficiency of this process remains low. In the July issue of G3, Srirattana and St. John report a method to deplete cattle donor cells of mitochondrial DNA and efficiently generate blastocysts from…

Hot wings and snow birds: Extreme temperature adaptation in domestic chickens
Humans built the modern world with the help of domestic plants and animals. A byproduct of our many domestication experiments is a series of excellent long-term controlled evolutionary comparisons that are helping geneticists understand adaptation. In a study published in the May issue of G3, Fleming et al. identify genomic regions under natural selection in…

The Genetic History of Horses
Like any revolutionary technology, domestic horses changed human society. The incredible speed and strength of these animals opened up new opportunities to spread trade, language, and culture. For thousands of years, horses have been helping build human society by pulling wagons and plows and carrying soldiers and travelers on their backs. Horse husbandry changed humanity,…

Sewall Wright: Evolving Mendel
In 1931, Sewall Wright—a quiet American geneticist specializing in livestock and guinea pigs—published a GENETICS paper that changed how we study evolution. Wright’s “Evolution in Mendelian populations” was one of the founding documents of population genetics and was among the first formal frameworks to reconcile Mendel’s laws of inheritance with Darwin’s vision of natural selection.…

Anxious chickens as a model for human behavior
Chickens that “chicken out” in unfamiliar surroundings may shed light on anxiety in humans, according to research published in the January 2016 issue of the journal GENETICS. Domestic chickens are much less anxious than their wild cousins, the red junglefowl. The new research identifies genes that contribute to this behavioral variation and reveals that several…
