In which plant does the inheritance of flower color not follow Mendelian principles?

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

Mendel did not propose which of the following?

In case of incomplete dominance,what is the observation 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 Mendelian cross,the $F_2$ generation shows that both the genotypic ratio and the phenotypic ratio are the same,i.e.,$1:2:1$. This indicates:
