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?
