TABLE 3

Predicted genotypic indicator variable and its probability distribution for the nine flanking marker genotypes in F2 progeny

Marker genotypej = pj(+1) – pj(–1)Pr(m1j, m2j)
m1j = 1, m2j = 1 Embedded Image ¼(1 – r)2
m1j = 1, m2j = 0 Embedded Image ½r(1 – r)
m1j = 1, m2j = 1 Embedded Image ¼ r 2
m1j = 0, m2j = 1 Embedded Image ½r(1 – r)
m1j = 0, m2j = 00½[r2 + (1 – r)2]
m1j = 0, m2j = 1 Embedded Image ½r(1 – r)
m1j = 1, m2j = 1 Embedded Image ¼ r 2
m1j = 1, m2j = 0 Embedded Image ½r(1 – r)
m1j = 1, m2j = 1 Embedded Image ¼(1 – r)2

pj(+1) = Pr(xj = +1|m1j, m2j) and pj(–1) = Pr(xj = –1|m1j, m2j).
