Meis1 is maternally imprinted in M . domestica fibroblasts. A) Histone profiles of Meis1. Two MOAs (two green scans), two MORs (two red scans), assembly gaps, annotated promoter CpG island, and the gene annotation. Significant histone peaks (MACS, p ≤ 10-5) are indicated by blue bars above the scan peaks. B) Enlargement of the genomic segment including and flanking both sides of the promoter region of Meis1. C) Genomic DNA and cDNA genotypes of one animal from each reciprocal cross. Percent of maternal allele contribution as determined by pyrosequencing is shown in each box.
