Threshold-dependent gene drives in wild populations

The

BioScience Talks podcast

features discussions of topical issues related to the biological sciences.

By altering the heritability of certain traits, gene drive technologies have the potential to spread desired genes through wild populations. In practice, this could lead to mosquito populations that, for example, bear traits making them resistant to the spread of malaria. Despite the huge potential for improving human well-being, concern exists that gene drives could fail in the wild or, perhaps more concerning, spread beyond their intended target populations.

Writing in


BioScience


, Dr. Greg Backus, a postdoctoral researcher at the University of California, Davis, and Jason Delborne, Associate Professor of Science Policy and Society at North Carolina State University’s Genetic Engineering and Society Center, describe a potential solution. Threshold-dependent gene drives could limit the spread of wild-released gene drives to target populations, increasing control and reducing the risk of unchecked spread. The authors joined us on this episode of

BioScience Talks

to discuss the potential of these gene drives–and also some of the questions of controllability, spread, and ecological uncertainty that relate to them.
