As long as present-day races are so overloaded with inferior and degenerate strains, race intermingling on a large scale would be most detrimental, but most of the objections to such experiments rest on social and cultural prejudices rather than on biological considerations. Even among inferior stocks, hybrids often are an improvement on their ancestors. Hybridization makes for species improvement because of the role of the dominant genes. Racial intermixture increases the likelihood of a larger number of the desirable dominants being present in the hybrid.
