In the case of incomplete dominance,what will be the proportion of progeny with the $Rr$ genotype in the $F_2$ generation (in $\%$)?

What does the given experiment demonstrate?

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 $\%$)?

Which of the following phenomena is observed in the plant $Mirabilis \text{ } jalapa$?

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:

In which of the following is incomplete dominance observed?
