What does the Andalusian fowl exhibit?

The phenomenon of incomplete dominance was observed by

In $Antirrhinum$ (Snapdragon),a cross between a white-flowered recessive plant $(ww)$ and a red-flowered dominant plant $(RR)$ results in $180$ plants in the $F_2$ generation. How many of these plants will have the same genotype as the parents?

In $Mirabilis$ $jalapa$,when a homozygous red-flowered plant is crossed with a white-flowered plant,all $F_1$ plants produce pink flowers. When $F_1$ plants are self-pollinated,the resulting $F_2$ generation produces red,pink,and white flowers in the ratio of:

Describe incomplete dominance.

In the case of incomplete dominance,what will be the phenotypic ratio in the $F_2$ generation?
