Figure 1.—

Model of genetic drift used for computer simulations of the recurrent selection population under analysis. Each bordered box specifies a population with letter designations indicating the type of mating used (FS, full sib; S₁, selfing) and number of individuals used (N) in establishing each of them. The shaded pentagons relate generations to cycles or stages of the breeding scheme (C₀, cycle 0; C₁, cycle 1; C₂, cycle 2; C₃, cycle 3; C₄, cycle 4; and seed increase 1 and 2). Cycle 0 corresponds to the progenitor population. The arrows indicate the direction of advancing generations and dashed lines indicate which generations were sampled.
