Abstract
The prevailing theory that normal intelligence and mild mental retardation are determined by multiple additive genes is critically reviewed in the light of findings from recent population studies. Discrepancies between theoretical concepts and reported data are noted, particularly those concerning frequency of mild mental retardation, sex ratio, and additional somatic and psychiatric handicaps in populations with mild mental retardation.Keywords
