“…Parents can influence the phenotype of their offspring through a range of mechanisms, including the transmission of nutrients or other cytoplasmic factors, such as hormones and proteins, or, in some cases, through epigenetic processes, such as CpG methylation, histone modifications and variants, or non-coding RNAs. The transmission of epi genetic marks between generations (transgenerational epigenetic inheritance via the gametes) is of particular interest because it has the potential to explain many examples of transgenerational phenotypic effects that are not easily accounted for by inherited genetic variation 113 .…”

“…Recent data from both animals and plants indicate that epigenetic resetting is not always complete and hence that acquired epigenetic states may be transmitted from parents to offspring ('germ-line epigenetic inheritance' or 'incomplete epigenetic resetting' or 'incomplete epigenetic reprogramming'; e.g. [6][7][8][9][10][11][12][13][14] reviewed in [4,5,[15][16][17][18][19]). …”

Resetting of epigenetic marks, such as DNA methylation, in germ cells or early embryos is not always complete. Epigenetic states may therefore persist, decay or accumulate across generations. In spite of mounting empirical evidence for incomplete resetting, it is currently poorly understood whether it simply reflects stochastic noise or plays an adaptive role in phenotype determination. Here, we use a simple model to show that incomplete resetting can be adaptive in heterogeneous environments. Transmission of acquired epigenetic states prevents mismatched phenotypes when the environment changes infrequently relative to generation time and when maternal and environmental cues are unreliable. We discuss how these results may help to interpret the emerging data on transgenerational epigenetic inheritance in plants and animals.
