As ancient humans spread across the globe from their evolutionary birthplace in Africa, they tended to lose a little genetic diversity at each step along the way. New settlements were probably often founded by small groups that carried only a subset of the total diversity present in their homelands. Successive rounds of this “founder effect”…

A vast number of species depend on sexual reproduction for survival. Sex facilitates adaptation and rids populations of deleterious mutations. Despite the benefits of this process, sex can be remarkably costly and disrupt already advantageous genetic combinations. Only 20% of fungal species have been observed to reproduce sexually, and a long-standing mystery for researchers is…

Primary ciliary dyskinesia (PCD) is a disorder characterized by chronic respiratory distress that has a history of going undiagnosed. Combined whole-exome sequencing (WES) and copy-number variant (CNV) analysis can aid in diagnosing patients with PCD, according to research published in G3 this month. PCD arises from mutations in cilia-associated genes—and results from the paralysis of…

Mark Blaxter (Institute of Evolutionary Biology, University of Edinburgh) reports on the “Caenorhabditis Genomes Project” workshop at GSA’s recent 20th International C. elegans Meeting. Caenorhabditis elegans, affectionately referred to as “the worm,” is one of the prettiest and most informative of the model organisms. It is see-through, has a simple lifecycle and a remarkably simple anatomy,…

The Genetics Society of America (GSA) is pleased to be a founding member of the Plant Science Research Network (PSRN), which was launched earlier this week. This effort, supported by a Research Coordination Network award from the National Science Foundation (NSF), will seek to unite the plant science community and to harness its collective vision…

For Lake Whitefish, history has repeated itself. Across the St. John River region that spans Québec and Maine, these freshwater fish have continually evolved in the same way. Within the many individual lakes in this area, Lake Whitefish have diverged into two groups differentiated by size and body shape. These two groups, known as “dwarf”…

The sticky fruit of the date palm has a tangled history. New research in G3 explores the palm’s genetic diversity and traces its earliest cultivation to at least two distinct regions in North Africa and the Arabian Gulf. The date palm (Phoenix dactylifera) is one of the world’s oldest cultivated trees and has close ties…
