  • For scenario 9 (Table 1). A1 and B1 are the two alleles at locus 1; A2 and B2 are the two alleles at locus 2. 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 the same genotype A1A2/B1B2. For linkage phase II, female and male parents have genotypes A1A2/B1B2 and A1B2/B1A2, respectively. For linkage phase III, female and male parents have genotypes A1B2/B1A2 and A1A2/B1B2, respectively. For linkage phase IV, female and male parents have the same genotype A1B2/B1A2.
