  1. Inverse Medea is a two-component system with a zygotic toxin and a maternal antidote. Thus the heterozygous offspring of the wildtype mothers have reduced viability (\(1-d_{im}\)). In Semele the males carry the toxin while the females carry the antidote. Thus offspring inheriting no antidote from their mothers have reduced viability (\(1-d_s\))
