Multifunctional redundancy (exponent a) dependence of the prokaryotic community (SR = 478) on the orthologue ratio randomly chosen in simulations from 197 061 orthologues. In 10–99% of cases, the median values from 200 permutations of randomly chosen orthologues are shown. Only median values are indicated because variation among the 200 permutations was very small. The maximum and minimum values among 200 permutations were very close to the median value (i.e. approx. 0.1% from the median).
