Selection for different genotypic classes (a) opaque2 and (b) waxy1 genes in the F₂ population of Pop1. Selected homozygous genotypes (1) o2⁺o2⁺/wx1⁺wx1⁺, (2) o2o2/wx1⁺wx1⁺, (3) o2⁺o2^+/wx1wx1, and (4) o2o2/wx1wx1. P1 and P2 represents parents with o2o2/wx1⁺wx1⁺ and o2⁺o2⁺/wx1wx1 genotype, respectively.
