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

In $Mirabilis \text{ } jalapa$, when homozygous red-flowered and white-flowered plants are crossed, all $F_1$ plants have pink-coloured flowers. What will be the phenotypic ratio in the $F_2$ generation produced by selfing of $F_1$ individuals?

In a cross between male and female pea plants,both are heterozygous for round seeds,what percentage of the progeny will be having intermediate sized starch grains (in $\%$)?

$A$ 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?

When the progeny obtained in the $F_1$ generation shows the expression of both genes present in its genotype, but the expression is not complete, which of the following characteristics can be applied?

Which of the following plants does $NOT$ exhibit incomplete dominance?
