Figure 2. Sex-biased gene expression.
a, Number of sex-biased DEX genes in brain regions/NCX areas during fetal development (periods 3–7), postnatal development (periods 8–12), and adulthood (periods 13–15). b, PCDH11Y exon array signal intensity (left) and qRT-PCR validation (right) (N=5 male brains per period). c, IGF2 exon array signal intensity (left) and qRT-PCR (right) validation in NCX (N=4 per sex and period). P-values were calculated by unpaired t-test. Whiskers indicate 5th and 95th percentile.
