TABLE 1

Predicted genotypic indicator variable and its probability distribution for the four flanking marker genotypes in backcross progeny

Marker classj = pj(1) = Pr(xj = 1|m1j, m2j)Pr(m1j, m2j)
m1j = 1, m2j = 1(1 – r1)(1 – r2)/(1 – r)(1 – r)/2
m1j = 1, m2j = 0(1 – r1)r2/rr/2
m1j = 0, m2j) = 1r1(1 – r2)/rr/2
m1j = 0, m2j = 0r1r2/(1 – r)(1 – r)/2

r is the recombination frequency between m1 and m2.
