In Antirrhinum majus a plant with red flowers was crossed with a plant with white flowers. Work out all the possible genotypes and phenotypes of F1F1 and F2F2 generations, comment on the pattern of inheritance in this case?
When Antirrhinum majus, a plant with red flowers, was crossed with a plant with white flowers, the F1F1 hybrid was pink i.e. a middle colour between red and white will appear which indicates that both red and white are incompletely dominant. When F1F1 individuals were self-pollinated, the F2F2 generation consists of red, pink and white flowers that appear in the ratio of 1:2:1 respectively. The pattern of inheritance of flower colour in snapdragon or Antirrhinum majus is an example of incomplete dominance.
