In DNA& Imprinting, Hannah and Angelos explore how 50% of our DNA comes from each parent, but only 1% "remembers" its origin. These male and female patterns of padlocks (DNA methylation and other epigenetic modifications) are both needed to make a healthy baby... but could this change? And what, really, is the difference between Ligers and Tigons? Featuring Dr Gavin Kelsey (Head of the Epigenetics programme at the Babraham Institute, Cambridge).
