  1. Pouch young and adult tissues analysed for INS imprinting via direct sequencing. Both female (F) and male (M) samples had monoallelic, biallelic or biased (>) expression. Some tissues had very low RT-PCR amplification (low) or no amplification (absent) so imprinting could not be determined. Three pouch young with a known maternal genotype showed paternal (Pat) monoallelic expression in the liver. nd, not determined.
