Conserved organization of the Dlk1-Gtl2 regions in mouse, human, and sheep. Above colored panels that describe sequence conservation and distribution of repetitive elements in the analyzed sequences, the structures of Dlk1 (dark blue), the transcript downstream of Dlk1 (light blue), and Gtl2 (red) are indicated by bars that represent exons. Arrows above the depicted exons indicate the orientation of gene transcription.
