Epigenetics Between the Generations (image) Max-Planck-Gesellschaft Share Print E-Mail Caption Egg-cell of a female fruit fly with the egg cell in which H3K27me3 was made visible through green staining. This cell, together with the sperm, will contribute to the formation of the next generation of flies. In the upper right corner, a maternal and paternal pre-nucleus are depicted before their fusion during fertilization. The green colouration of H3K27me3 appears exclusively in the maternal pre-nucleus, indicating that their epigenetic instructions are inherited into the next generation. Credit MPI of Immunobiology a.
