Madison Blumer ’15 on sex chromosome turnover in bent-toed geckos in a special issue of Genes, which focused on the evolution of chromosomes in vertebrates. Although squamate lizards, or scaled reptiles, have diverse sex chromosome systems, the turnover rate in bent-toed geckos is even more frequent than in other lizards of the order Squamata. The data suggests that this turnover makes geckos an important model for further study of sex chromosome evolution.
