Figure 4. Explanation of the compatiblity relationship using the goalkeeper-model.

Figure 4

The points represent the contribution by the corresponding Wolbachia strain to the two mod factors (Inline graphic and Inline graphic). The black arrow represents the host contribution to rescue. The contribution of a strain to the two resc factors equals its own contribution plus the net host contribution. When both resc factors exceed both mod factors in quantity, rescue is successful. Thus wTei with the help of the net host contribution rescues wRi (indicated by wRi being within the dotted frame). In contrast, wRi can rescue wMel but not wTei (indicated by wMel but not wTei being within the dashed frame).
