Results are reported from studies on the stability of balanced polymorphism in populations of Drosophila paulestorum and Drosophila willistoni. These populations naturally contain more than 50% heterozygotes for certain inversions. Data are tabulated. It was concluded that these populations did not possess genetic materials from which monomorphic genetic systems conferning high adaptedness could be built. The evolutionary aaantages of genetic systems based on balanced polymorphisms are discussed. (C.H.)
