Thanks to more than a hundred years of working with Drosophila melanogaster, geneticists have many powerful tools for precisely manipulating its genes. It has also...


Constant mutation and shaping by natural selection can make the once-identical genomes of isolated populations of organisms very different from one another. This genetic divergence...


GSA is an official partner of the March for Science—we hope you will join us in marching on Earth Day, April 22! You can now wear...


In the genomic era, population geneticists are flooded with molecular data on the evolution of natural populations. This deluge started in 1966 as a trickle...


We are pleased to announce that Richard C. Lewontin, PhD is the 2017 recipient of the Thomas Hunt Morgan Medal for lifetime achievement in the field...


We are pleased to announce that David Kingsley, PhD is the 2017 recipient of the GSA Medal for outstanding contributions to the field of genetics...


When geneticist Rob Unckless took his son to Lego Club at the local library, he was not expecting to start a new collaboration. The result...


Despite being covered by a massive, permanent ice sheet, Greenland has been continuously inhabited by humans for over a thousand years. Most modern Greenlanders are...


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...


Sex chromosomes have evolved from autosomes hundreds of times across the tree of life. In mammals, sex is controlled by the Y chromosome-linked gene SRY,...
