Table 1.

Comparisons of ω_a between X- and autosomal-linked genes among different categories of sex-biased gene expression. The table displays the means and 95% bootstrap confidence intervals (in parentheses) of ω_a for each category of gene expression.

expression bias	X	A	Mann–Whitney p-value
male	0.159 (0.144, 0.174)	0.095 (0.083, 0.109)	0.0008
unbiased	0.083 (0.072, 0.091)	0.051 (0.039, 0.064)	0.014
