title: Size advantage may not always favor sex change.
abstract: A simple application of sex allocation theory to sex reversal suggests that, under Ghiselin's size advantage model, this form of sexuality ought to be common; actually it is quite rare. This note suggests that a sex specific size advantage may not favor sex change if the advantage is offset by other life-history tradeoffs. A few possibilities are discussed.
