Table 3 Possible segregation ratios of progeny resulting from crosses of repeat-fruiting (RB) and once-fruiting (jb) commercial strawberry parents. Possible progeny ratios are listed on the left. Parental combinations that would result in each segregation ratio are provided for the known mapped dominant gene conferring repeat fruiting with no suppressor, with a hypothetical dominant suppressor, or with a recessive suppressor of the known dominant gene
