Whether a thunderclap drives your dog to cower behind the couch or leaves it unfazed may be determined in part by genetics. In the June...


Fascinating discoveries sometimes emerge from the most daunting of experimental roadblocks. Designed to generate over 1,000 recombinant inbred mice lines for genetic mapping, the Collaborative...


When a horse is born with naked foal syndrome (NFS), it will likely die early. This genetic skin condition affects the Akhal-Teke horse breed from...


Take two neighboring cells from the same tissue—cells that are about as identical as any could be. Despite their similarities, these two cells could actually...


Recombination within the genome isn’t random. This swapping of DNA segments between one chromosome and its homolog preferentially affects specific genome regions called hotspots. These...


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,...


A genomic analysis of 28 dog breeds has traced the genetic history of the remarkable Fonni’s Dog, a herd guardian endemic to the Mediterranean island...


The mild temperament that distinguishes the family dog from its wolf ancestors is just one of a whole array of traits that seem to have...


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...
