Before revision: We study families of chemical reaction networks , with toric steady states . Larger family members are constructed algorithmically from a smallest networkand we show that many results about the entire family can be obtained by studying the small family members only. In particular, we prove that if a small family member is multistationary, then so are all of its larger members .
