The croaking gourami (Trichopsis vittatus) exhibits two phenotypes associated with humeral spotting. Fish possess a prominent, dark humeral patch or spot located behind the operculum or lack this spotting pattern. Segregation patterns observed from the progenies of eleven different crosses support the hypothesis that the inheritance of humeral spotting in T. vittatus is controlled by the action of a single autosomal locus, with complete dominance of the allele controlling the spotted phenotype.

Ten years ago, observers warned that foreign direct investment in the new democracies of Central and Eastern Europe (CEE) would be stymied by the problem of environmental liability for past pollution. CEE governments responded by granting some investors exemptions from liability for past pollution. Nevertheless, during the 1990s, many investors steered away from contaminated properties, opting to construct new facilities in more pristine areas. Increasingly, in Western Europe and the United States, governments view liability for past pollution as one aspect of the broader problem of attracting wary investors to old, industrial properties or “brotunfields. “CEE governments can gain by considering the applicability of Western-style brownfields revitalization policies and programs to the CEE context. CEE governments can adapt legal and regulatory aspects of brownfields cleanup programs. But, the financial demands of brownfields cleanup are insurmountable in CEE without stepped-up economic assistance from external actors.
