Blame Your Mother

genetics > genes > more than
"Mice with virtually identical genes can grow into quite different-looking animals—fat and yellow, or lean and brown—depending on what their mothers ate during pregnancy. As this ScienCentral News video reports, researchers are studying a twist to heredity that goes beyond our genes."
Slowly but surely the mechanistic approach to genotypes, phenotypes and their relation is being eroded.
Meanwhile gene regulation is turning out to be connected to a strictly choreographed histone dance, possibly dictated by "a complicated non-DNA code".
