Selection of sex-ratio and the evolution of sex-determination

Heredity (Edinb). 1975 Jun;34(3):351-61. doi: 10.1038/hdy.1975.44.


Deterministic selection forces operating at a modifier level within a population lead to the establishment of systems of sex-determination which, under a variety of natural conditions, induce sex-ratios close to 1 : 1.
