Joint Probabilities of Three-Locus Genotypes for a Putative QTL Bracketed by Two Simplex Markers Under Different QTL-Marker Linkage Phases as Given in Expressions 2 Through 4 in a Pseudo-Test Backcross Design.

The conditional probabilities of the QTL genotypes upon the marker interval are calculated according to Bayes' theorem. 

There are two marker genotypes 1000 and 0000 for each marker in the pseudo-test backcross design 1000 × 0000. The recombination fractions between the left marker of the interval and the QTL, and the QTL and the right marker of the interval are denoted by r₁ and r₂, respectively. The preferential pairing factor is denoted by p.
