What does the Andalusian fowl exhibit?

In the phenomenon of incomplete dominance observed in $Antirrhinum$ $majus$ (Snapdragon),what is the phenotypic ratio of the progeny in the $F_2$ generation?

In incomplete dominance,which ratio does not match with Mendel's monohybrid cross?

When a pure red-flowered $(RR)$ snapdragon plant is crossed with a pure white-flowered $(rr)$ plant,the $F_1$ generation produces pink flowers. When this $F_1$ progeny is self-pollinated,the resulting $F_2$ generation ratio is $1$ $(RR)$ red : $2$ $(Rr)$ pink : $1$ $(rr)$ white. This phenomenon can be explained by:

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

Genotypic and phenotypic ratios remain the same in
