Table 1 Parameters of the model

From: Evolution of variation in presence and absence of genes in bacterial pathways

Symbol Range or value Meaning
n [1, 30] the number of genes in the pathway
c [0, 0.01] the fitness cost per gene to a single genome
ε [0, 1] the exposure probability (of encountering the selective environment)
b 0.1 the fitness benefit conferred by the whole pathway
δ 10−9 the probability of deletion of a single gene per generation
γ 1 [10−9, 10−3] the transfer probability for 1 gene per generation
κ [0.1, 1] the transfer decay parameter, modelling clustering
