Fig. 2. Probability q_g that at least one BC progeny with genotype t⁺ T⁺ is generated by backcrossing individuals of Genotype g G₀. In the left diagram (A), the family size f_g derived from one backcrossed individual (i_g = 1) is increased. In the right diagram (B), the number of backcrossed individuals i_g is increased for family size f_g = 1. Marker distances are d₁ = d₂ = 0.10 M and ₁ = ₂ = 0.02 M.
