摘要：

A two-locus diploid model is developed in order to analyze stable mother's and offsprings' strategies concerning the offsprings' sex determination and progeny's sex ratio when the cost of rearing a male offspring is different from the cost of rearing a female offspring. It is shown that if the ratio in cost is lambda:1, then the resulting stable sex ratio in the population lies between the value 1:lambda, obtained with full mother's control, and 1:lambda-1/2, obtained with no maternal interference. The effects of biologically relevant parameters on the sex ratio and sex determination are investigated.
