The phenotypes of the progeny are indicated by the shading of the cells in the table: black coat (black, E_B_); chocolate coat (brown, E_bb); yellow coat (yellow, eeB_ or eebb). For a trihybrid cross, the F 2 phenotypic ratio is 27:9:9:9:3:3:3:1. The dominant trait is expressed in 3/4 of the offspring. Mendel’s experiments included trihybrid crosses in which he tracked inheritance patterns for three pairs of traits in a single series of crosses. A particularly efficient method of mapping three genes at once is the three-point cross, which allows the order and distance between three potentially linked genes to be determined in a single cross experiment (Figure 7.
