In snapdragon / antirrhinum, hybrid between red and white flowered plants is pink flowered. This is .

In $F_2$ generation of monohybrid cross the cause of $1 : 2 : 1$ phenotypic ratio is

$A$ : 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

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

$RR$ $(Red)$ is crossed with $ww$ $(white)$, all the $Rw$ offsprings are pink. This is an indication that $R$ gene is

In Mirabilis, a hybrid for red $(RR)$ and white $(rr)$ flower produces pink $(Rr)$ flower. A plant with pink flower is crossed with white flower, the expected phenotypic ratio is
