Transitional probabilities P cn , P cc , P nn , P nc , P nm for λ = 2/3, μ= 1/6. In this case the probability of conservation of the consensus nucleotide is less than the probability of conservation of a non-consensus nucleotide, P cc (u) <P nn (u) for u ∈ (0, u**), since 3λ > 2μ + 1 and λ > μ. The stationary distribution of the consensus state is π c = 1/3. Thus, the consensus is weak. Since μ <λ, we have P cn (u) > P nm (u) for all u > 0.
