Incomplete dominance is observed in . . . . . . .

Which of the following plants does $NOT$ exhibit incomplete dominance?

In incomplete dominance,

In Antirrhinum,two plants with pink flowers were hybridized. The $F_1$ plants produced red,pink,and white flowers in the proportion of $1$ red,$2$ pink,and $1$ white. What could be the genotype of the two plants used for hybridization? Red flower color is determined by $RR$,and white by $rr$ genes.

When two homozygous plants with red and white flowers are crossed, their offsprings show pink flowers. This indicates that the alleles of the gene for flower colour shows . . . . . . .

The synthesis of starch in pea seeds is controlled by a single gene. This gene has two alleles,$B$ and $b$. If the size of the starch grain is considered as the phenotype,what type of inheritance does this represent?
