Consider Mendel's experiments involving the trait of round versus wrinkled peas. In some experiments, Mendel removed the anthers of the flowers from a plant that was true-breeding for round peas and applied pollen from the anthers of a plant that was true-breeding for wrinkled peas. What would have happened if Mendel missed some anthers that he was trying to remove from the true-breeding round pea plants, and then counted the peas produced by a plant that bore a mix of round and wrinkled pollen? Indicate which of the following must be TRUE. A)The F₁ peas produced would have mixed phenotypes. B)The F₁ peas produced would have a single phenotype. C)The F₂ peas would have phenotypes in a 9:3:3:1 ratio. D)The F₂ peas would all have the phenotype of the parental plant with the anthers not properly removed. E)The F₁ peas would have phenotypes in a 1:1 ratio.

If Mendel missed some anthers, the F1 generation would still show a single phenotype (round peas) because round is dominant over wrinkled.
