Associate Professor of Biology Patrick Ferree, Emily Yuguchi ’19, Haena Lee ’18, and Salina Teklay ’22 coauthored a paper, published in Nature, on B chromosome behavior in the jewel wasp. Despite being nonessential, B chromosomes often exhibit behaviors that enhance their own transmission. “A fundamental but poorly understood question is what characteristics allow B chromosomes to exhibit these extraordinary behaviors,” the coauthors write. By performing fluorescence microscopic analyses, the researchers determined that the paternal sex ratio B chromosome in jewel wasps “may target an aspect of euchromatin to cause genome elimination.”
