  • The effective size of the parental population is 104. Predictions in the second column are made using deleterious mutation parameters λ = 0.4, Embedded Image = 0.03, Embedded Image = 0.36, β = 1 from set I and predictions in the third column are made using deleterious mutation parameters λ = 0.03, Embedded Image = 0.15, Embedded Image = 0.36, β = 3 from set II. Lethal mutation parameters are ㎻ = 0.015 and Embedded Image = 0.03 in both predictions.
