Higher fold-change expression sex difference for the Z chromsome than for individual autosomes. Box plots showing median of log2 male-to-female fold-change values per chromosome in (a) soma and (b) gonads. Boxes represent the mid 50% of the data (first and third quartiles) and whiskers extend to the minimum and maximum values that are not outliers (defined as >1.5 units away from first and third quartiles. Data from the Z chromosome is shown in red.
