Pipe 2THT Embryos Receive Parent-Specific Layers of Information

Embryos Receive Parent-Specific Layers of Information

by
in science on (#2THT)
Not long ago we had a somewhat controversial article here:
http://pipedot.org/story/2014-10-06/offspring-can-resemble-a-mothers-previous-mate

Here is a similar one:

'Similar' in a very broad sense of this word. It shows that there are still plenty of unknown factors in
human and non-human reproduction.
The research, detailed in an article published in the journal PLOS Genetics, sheds light on
the multilayered process of how a sperm and egg pass along information needed for successful
reproduction. Though one layer is the DNA code that is transferred, the new study identifies
information not encoded by DNA, a so-called “epigenetic” layer of information that helps the
cell interpret the genetic code.
In insects this additional “epigenetic” layer of information apparently can come from a previous mate.
The question if such or similar mechanisms can also exist in higher organisms, e.g. also in humans, might be
far fetched, but not that far, that it precludes a more thorough research.
