The DNA of a body does not naturally change (in any organized way).  Cells pass on changed DNA only to their progeny.  Only genetic changes to gametes will be passed on genetically to children.<p>However, the regulation of DNA can be transmitted.  One can turn genes on and off throughout the body by exposing the cells to particular signals such as hormones.  But those don&#x27;t change the DNA, they just change the interpretation and usage of the DNA that&#x27;s already present.
