  1. The analysis compares the four types of tests: specialized parasites on their own host, specialized parasites on mismatched hosts, parasites evolved on mixtures of hosts and parasites evolved on alternating hosts. 'Evolution regime' refers to the isofemale line (or combination of lines) the parasites evolved on.
