Charnov's prediction that hermaphroditism would occur under circumstances where Bateman's principle does not apply is found to be largely correct.
However, the prediction as to the association of hermaphroditism and low fixed costs is inconsistent with the data.
Alternative explanations that predict that hermaphroditism is a strategy for reducing variance in reproductive success may better explain the data.
Probability theory demonstrates that where two strategies have equal mean fitness, which must be the case for male and female function, the strategy with the lower variance in reproductive success must have higher fitness (Gillespie's principle).
