 If introduced into a population at sufficiently high levels, the "Medea" gene will spread, replacing entire populations of normal beetles with beetles carrying "Medea".Because of this, "Medea" has been proposed as a way of genetically modifying insect populations.By linking the "Medea" construct to a gene of interest - for instance, a gene conferring resistance to malaria - "Medea"'s unique dynamics could be exploited to drive both genes into a population.
