What would be the colour of flowers in $F_1$ progeny as a result of a cross between homozygous red and homozygous white-flowered Snapdragon

Describe incomplete dominance.  

A pink flowered Snapdragon plant was crossed with a red flowered Snapdragon plant. What type of phenotype/s is/are expected in the progeny?

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, $2$ pinkand $1$ white. What could be the genotype of the two plants used for hybridization ? Red flower colour is determined by $RR$, and white by $rr$ genes?

In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in $\mathrm{F}_{1}$ generation, pink flowers were obtained. When pink flowers were selfed, the $\mathrm{F}_{2}$ generation showed white, red and pink flowers.
