\( \left (\begin {array}{rr} 1& 0 \\ 0& 1\\ \end {array} \right) \)	\( \left (\begin {array}{rr} 0& 1\\ 1& 0\\ \end {array} \right) \)	\( \left (\begin {array}{rr} 0& 1\\ 1& 1\\ \end {array} \right) \)	\( \left (\begin {array}{rr} 1& 0\\ 0& 0\\ \end {array} \right) \)

The infection matrices determine the outcome of the interaction between host genotypes (rows) and parasite genotypes (columns). To keep the illustration simple, the rates α_ij are either chosen as one for infection or as zero for resistance. Matching-allele and gene-for-gene models are shown as well as their inverse versions
