Mathematical models in population genetics, such as diffusion approximations and coalescent theory, allow researchers to calculate the expected time for a neutral allele to reach a given frequency.

The analysis

The claim is specific, empirical, and well-established in evolutionary theory. Multiple provided papers discuss mathematical derivations for the time it takes for neutral alleles to reach specific frequencies or fixation using tools like diffusion approximations and coalescent theory.
