Certain genes have apparently unusual inheritance patterns. for instance, in the mouse autosomal gene h19, only the copy inherited from the mouse's mother is expressed. conversely, in the mouse autosomal gene igf2, only the copy inherited from the mouse's father is expressed. the consequence of this is that imprinted genes are expressed as if they were present in only one copy, even though there are two copies of each of these genes in each cell. what process or processes are responsible for this phenomenon
