Abstract
ENZYME polymorphisms are known to be widespread in natural populations1–3. No adequate theory has been advanced to account for their frequent occurrence; some workers support the proposition that they are selectively “neutral”4–6, while others present evidence that they are maintained in natural populations through natural selection rather than by non-selective processes1,7–9.
