What is the other name for "incomplete dominance"?

In incomplete dominance,each of the parental traits reappears in the $F_2$ generation by . . . . . . %.

In $Mirabilis$ and $Antirrhinum$ plants,the flowers appear pink in the hybrid $(Rr)$ condition,which is produced by crossing red $(RR)$ and white $(rr)$ parent flowers. This phenomenon is known as:

Genotypic and phenotypic ratios remain the same in

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?

$A$ grey-feathered chicken is crossed with another chicken of the same phenotype. The offspring are $15$ grey,$6$ black,and $8$ white. What will be the phenotype of the offspring produced by selfing the grey chickens and the black chickens from their progeny?
