The index of dispersion of molecular evolution: slow fluctuations.

Theoretical population biology - 1 Mar 2000

Cutler D J

Abstract excerpt

The most simple neutral model of molecular evolution predicts that the number of substitutions within a lineage in T generations ought to be Poisson distributed. Therefore, the variance in the number of substitutions ought to equal the mean number. The ratio of the variance to the mean number of substitutions is called the index of dispersion, R(T). Assuming infinite sites, no recombination model of the gene, and...
