Which cross yields red, white and pink flowers variety of dog flower?
RR × Rr
Rr × RR
Rr × Rr
Rr × rr
The correct option is B Rr $$\times$$ Rr The F1-hybrid plants have a different phenotype (pink flowers) than either of the true-breeding parents. This is an example of incomplete dominance. When the F1-hybrid plants are self-fertilized, both parental phenotypes (red flowered plants and white flowered plants) reappear in the F2 generation.
