Abstract
To circumvent the problem of frequency dependence, most genetic models for differential fertility impose severe constraints on parental interactions. In the present weak selection model these constraints are relaxed. Evolution treats mean family fertility as a Wrightian fitness function. This yields an intuitively simple means of predicting the results of extremely complicated genetic dynamics: selection will locally change gene frequency to maximize the occurrence of the most fertile matings. If matings by and among heterozygotes produce the most offspring, stable polymorphisms may occur. If these matings are the least fertile, the occurrence of unstable polymorphisms may be expected.
