 The discussion above tried as much as possible to present a unified framework for the discussion of inheritance systems that is not tied to any particular account. It contrasted the multiple inheritance systems view with monist (i.e., geno-centrism) and holistic views (i.e., DST) about inheritance  (section 1.3)  and stressed the developmental, mechanism-oriented, perspective on reproduction that underlies many discussions of inheritance systems (see  section 2).
