Texas State University researchers have contributed to groundbreaking research that has identified the formation of a new sex chromosome in Xiphophorus fish.
Texas State’s Ron Walter, director of the Xiphophorus Genetic Stock Center and professor in the Department of Chemistry and Biochemistry at Texas State, collaborated with an international team led by Paolo Franchini of the University of Konstanz, Germany, on the project. Other collaborators included Manfred Schartl, Department for Physiological Chemistry at the Biocenter of the University of Würzburg, Germany, and Wesley Warren, McDonnell Genome Institute, Washington University School of Medicine in St. Louis.
The findings, “Long-term experimental hybridization results in the evolution of a new sex chromosome in swordtail fish,” are published in the journal Nature Communications. The paper may be found online.
