Are females more variable than males in gene expression? Meta-analysis of microarray datasets

Table 1 Tissue-specific sex bias of gene expression variation. Four mouse tissues were separately analyzed as examples, and histograms for spleen and adrenals were shown in Fig. 2 (GSE9904, GSE9907, GSE9908, GSE9895: [12])
