The theoretically possible patterns of specificity in a mutualistic host-symbiont interaction. a. Mutually high specificity. One host lineage is exclusively associated with a single symbiont lineage. b. Low symbiont specificity, high host specificity. A host lineage can be associated with three different symbiont lineages (low symbiont specificity), which each are specialized on that single host lineage (high host specificity). c. High symbiont specificity, low host specificity. Three different host lineages are each associated with the same symbiont lineage. d. Mutually low specificity. Three host lineages can all be associated with three different symbiont lineages.
