Topics Covered

• When does epigenetic reprogramming during the transfer of DNA between parents and their offspring occur, in the gametes or in early development?
• inheritance of epigenetic marks can occur, meaning that information other than DNA sequence can be passed on from parent to offspring
• the influence of parental environmental history on an individual's epigenetic state
• does epigenetic inheritance have an adaptive value?
• could epigenetic state be used to give a better estimate of disease risk?
