      abstract     = {Magnetic skyrmions are prime candidates as information
                      carriers for spintronic devices due to their topological
                      nature and nanometric size. However, unavoidable
                      inhomogeneities inherent to any material leads to pinning or
                      repulsion of skyrmions that, in analogy to biology concepts,
                      define the phenotype of the skyrmion-defect interaction,
                      generating complexity in their motion and challenging their
                      application as future bits of information. Here, we
                      demonstrate that atom-by-atom manufacturing of multi-atomic
                      defects, being antiferromagnetic or ferromagnetic, permits
                      the breeding of their energy profiles, for which we build
                      schematically a Punnet-square. As established from
                      first-principles for skyrmions generated in PdFe bilayer on
                      Ir(111) surface, the resulting interaction phenotype is
                      rich. It can be opposite to the original one and eventually
                      be of dual pinning-repulsive nature yielding energy
                      landscapes hosting multi-domains. This is dictated by the
                      stacking site, geometry, size and chemical nature of the
                      adsorbed defects, which control the involved magnetic
                      interactions. This work provides new insights towards the
                      development of disruptive device architectures incorporating
                      defects into their design aiming to control and guide
                      skyrmions.},
