COLLEGE PARK, Md. -- University of Maryland biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve. In research published in the journal Science (October 1, 2009),... |
