Modeling Neutral Evolution Using an Infinite-Allele Markov Branching Process

Figure 3

Comparison between the finite-time mean frequency spectrum and the limiting mean frequency spectrum of the infinite-allele birth and death process. (a) 𝜓_1𝑗(𝑡) and 𝜓_𝑗 for 1≤𝑗≤15, 𝑡=15,20,28 and ∞. (b) Difference between 𝜓_1𝑗(𝑡) and 𝜓_𝑗 as a function of 𝑡, 𝑡∈[15,35] for 𝑗=1,2. Lines represent the true difference and markers represent asymptotic approximations.
