  • For scenario 4 (Table 1). A1, B1, C1, and D1 are the four alleles at locus 1. A2 and B2 are the two alleles at locus 2. Recombination frequencies in the female and male parents are denoted as rF and rM, respectively. The combined recombination frequency is denoted as r. The last column gives the symbol of observed sample size of each genotype. For linkage phase I, female and male parents have genotypes A1A2/B1B2 and C1A2/D1B2, respectively. For linkage phase II, female and male parents have genotypes A1A2/B1B2, and C1B2/D1A2, respectively. For linkage phase III, female and male parents have genotypes A1B2/B1A2, and C1A2/D1B2, respectively. For linkage phase IV, female and male parents have genotypes A1B2/B1A2, and C1B2/D1A2, respectively.
