Epigenetics refers to a special kind of hereditary mechanism. Epigenetic changes do not change the DNA
nucleotide sequence, yet their effect on gene expression can last for several generations.
In one surprising study, it was found that the grandsons of men who suffered a famine were less likely to
die of cardiovascular disease. The experience of famine made some cardio-protective change in the
sperm of those grandfathers that was passed on.
What type of change was likely responsible?
