Imprinted genes. After removing genes on the sex chromosomes, similar numbers of genes were found to be expressed from the maternal allele (290 genes, colored pink) and from the paternal allele (245 genes, colored blue). The average log2 expression fold change between the two alleles in the initial cross hybrids (F1i) and between the two alleles in the reciprocal cross hybrids (F1r) is plotted on the y- and x-axis, respectively.
