Spletwhen dealing with a mixture of Poisson processes characterized by Γ-distributed rates, the number of substitutions per site is necessarily a negative binomial whose shape parameter is the same α (see chapter 2). The probability to have k substitutions at a site is then: P (k α, hki) = Γ (α + k) Γ (α) · k! hki hki + α !k · α hki + α !α (5.5) Splet23. dec. 2004 · The number of substitutions per site per unit of mass-specific metabolic energy, fν, can be calculated from the y-intercepts (C) in Figs. 1, 2, 3: fν = e C /b o (Eqs. 3 and 4). Taking the fitted intercept of C ≈ 26 for mtDNA , and b o = 1.5 × 10 8 W·g-3/4 , we obtain fν ≈ 4 × 10-13 g·substitutions·site-1 ·J-1.
