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 |
