$A$ : In snapdragon, $F_{1}$ plants do not have red or white flowers.
$R$ : It is intermediate inheritance with neither of the two alleles of a gene being dominant over each other

When a pink flowered Antirrhinum plant is test crossed, then phenotypic ratio in resulting progenies is

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?
