Genetic combinatorial explosion. Solutions of the equation Inline graphic, where n denotes number of genes in the genome, r is the number assumed to be involved in each function. Ordinate: number of possible combinations (potential biological functions). Abscissa: Number of genes required in each function. The curves show results for genomes of various sizes between 100 and 30 000 genes and for up to 100 genes involved in each function (adapted from Feytmans et al. [3]).
