In incomplete dominance,which ratio does not match with Mendel's monohybrid cross?

In snapdragon ($Antirrhinum$ $majus$),the hybrid between red and white flowered plants is pink flowered. This is an example of:

In the case of incomplete dominance,what will be the phenotypic ratio in the $F_2$ generation?

In $Antirrhinum$ $(Snapdragon)$,a red flower was crossed with a white flower and in $F_{1}$ generation,pink flowers were obtained. When pink flowers were selfed,the $F_{2}$ generation showed white,red and pink flowers. Choose the incorrect statement from the following:

In incomplete dominance,

The presence of the $Bb$ gene in pea plants results in intermediate-sized starch grains. Which phenomenon does this represent?
