We compare the structure of a mapping cone in the category Top^D of spaces
under a space D with differentials in algebraic models like crossed complexes
and quadratic complexes. Several subcategories of Top^D are identified with
algebraic categories. As an application we show that there are exactly 16
essential self--maps of S^2 x S^2 fixing the diagonal.
