University of Iowa News Release

 

Sept. 22, 2008

Battle of the sexes, chromosomally speaking, is subject of lecture Sept. 27

"Chromosomes Caught in the Battle of the Sexes: Advantage Female" will be the subject of a free, public lecture to be held at 10 a.m. Saturday, Sept. 27, in Room 40 of Schaeffer Hall.

Bryant McAllister, associate professor in the University of Iowa College of Liberal Arts and Sciences (CLAS) Department of Biology, will present the lecture and discussion session.

Part of the CLAS 2008 Saturday Scholars lecture series, the talk will begin by examining how differences between the sexes exist universally among animals and plants.

Although males and females share a common gene pool, the sex chromosomes control sex, and so they are not shared equally between females and males. Research by McAllister and his colleagues explores how this inequality influences the content and function of genes on the sex chromosomes. McAllister says that his studies involving fruit flies (Drosophila) indicate that selection pressures unique to females appear to have an overwhelming influence on the sex chromosomes.

McAllister joined the UI faculty in 2002 after earning a doctorate in biology from the University of Rochester and receiving an Alfred P. Sloan/National Science Foundation Postdoctoral Fellowship in Molecular Evolution. His primary UI teaching responsibility is an undergraduate course in evolution. In addition, he is a member of the Roy J. Carver Center for Comparative Genomics and a 2008 Dean's Scholar. Grants from the National Science Foundation and the Roy J. Carver Charitable Trust have supported his research.
