This article marks the 25th anniversary of a paper reporting the first sex-determination mutants to be found in the nematode Caenorhabditis elegans. The isolation of these mutants initiated an extensive analysis of nematode sex determination and dosage compensation, carried out by a number of laboratories over the subsequent decades. As a result, the process of sex determination is now one of the most thoroughly understood parts of C. elegans development, in both genetic and molecular terms. It has also proved to have interesting repercussions on the study of sex determination in other organisms.

The Genetics Society of America's (GSA) Thomas Hunt Morgan Medal honors researchers for lifetime achievement in genetics. The recipient of the 2018 Morgan Medal, Barbara J. Meyer of the Howard Hughes Medical Institute and the University of California, Berkeley, is recognized for her career-long, groundbreaking investigations of how chromosome behaviors are controlled. Meyer's work has revealed mechanisms of sex determination and dosage compensation in <i>Caenorhabditis elegans</i> that continue to serve as the foundation of diverse areas of study on chromosome structure and function today, nearly 40 years after she began her work on the topic.
