A mother's diet before conception can permanently affect how her child's genes function, according to a study published in Nature Communications. A 2003 study found that a female mouse's diet can change her offspring's coat color by permanently modifying DNA methylation.
I believe you mean mid-ocean ridge?
If so, true.
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.
This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.
