Because there are very few sex-limited genes, sex differences are largely a product of contrasting gene expression patterns between males and females4.
This slow divergence is accomplished by a breakdown of the genetic correlation between the sexes through the accumulation of sex-limited genes (Fisher 1958) and leads to the prediction that highly dimorphic traits will have low genetic correlations.
Once the sex-limited genes approach fixation, the sexes are less able to evolve independently.
