The percentage of male and female reproductive genes among those that have emerged on the Z-chromosome during avian evolution. Solid bars are genes specific to either testis or ovary, and open bars are genes with sex-biased expression in gonads. Error bars indicate the 95% confidence interval for the total proportion of sex-specific and sex-biased genes.
