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

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

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

Reason : Flower colour gene shows incomplete dominance.
