What is the other name for "incomplete dominance"?

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?

Describe incomplete dominance.

The $F_1$ hybrid is intermediate between the two parents. This phenomenon is known as:

$A$ white-flowered Mirabilis plant $(rr)$ is crossed with a red-flowered plant $(RR)$. If $120$ plants are produced in the $F_2$ generation, what will be the result?

In a Mendelian cross,the $F_2$ generation shows that both the genotypic ratio and the phenotypic ratio are the same,i.e.,$1:2:1$. This indicates:
