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 certain plant species, red flower colour is incompletely dominant to white flower colour (the heterozygote is pink) and tall stems are completely dominant to dwarf stem. If a tall pink plant $(TtRr)$ is crossed with a tall white plant $(TTrr),$ which one of the following type of plants would be produced in the offsprings?

Assertion : In Mirabilis, selfing of $F_1$ pink flower plants produces same phenotypic & genotypic ratio.

Reason : Flower colour gene shows incomplete dominance.

A plant with red flowers was crossed with another plant with yellow flowers. If $F_1$ showed all flowers orange in colour, explain the inheritance.

Incomplete dominance is found in

$A$ : 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
