Fisher noted that this one-mother/one-father symmetry generates frequency dependent natural selection on sex ratio, resulting in an evolutionary equi librium in which half of the reproductive resources are devoted to daughters and half to sons. Although widespread interest in sex ratio as a phenotypic trait did not occur for another 30 years, it is difficult for us to overestimate the impor tance of Fisher's brief and characteristically cryptic remarks.
