‘Supergene’ wreaks havoc in a genome
Rochester biologists have for the first time used population genomics to study a selfish ‘supergene’ known as Segregation Distorter (SD) that skews genetic inheritance.
More evidence of an evolutionary ‘arms race’ between genes and selfish genetic elements
Christina Muirhead, a computational biologist and population geneticist in the lab of Daven Presgraves, further proves genes develop weapons to combat ‘parasites’ that litter the human genome.
What makes a species different?
New Rochester research points to the presence of “selfish genes,” whose flow among species may dictate whether two species converge or diverge.
Scientists discover gene controlling genetic recombination rates
Some species have evolved to display far more genetic crossover than others—and scientists have discovered a gene in fruit flies that is responsible for the evolution of these recombination rates.
