Chromosomal scans of imprinting status. (a) Imprinting status for chromosome 11. (b) Imprinting status for chromosome X. Each plot contains unique Entrez genes covered by SNP-containing Illumina reads with counts no less than 4 in each reciprocal cross. The height of each bar is the difference of the AKR percentage in the two reciprocal crosses (p1-p2), representing the intensity of imprinting. The color indicates the direction of expression bias: blue for paternal over-expression and red for maternal over-expression. The intensity of the color represents the significance: grey for not significant (q-value ≥ 0.10), lighter blue and pink for marginally significant (0.05 ≤ q-value < 0.10), darker blue and red for significant (q-value < 0.05). The gene name is indicated for the instances where| p1-p2| ≥ 0.3. Data are from .
