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:

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 $\%$)?

In $Mirabilis \text{ jalapa}$, the phenotypic ratio of red : pink : white flowers in the $F_2$ generation is ....

The synthesis of starch in pea seeds is controlled by a single gene. This gene has two alleles,$B$ and $b$. If the size of the starch grain is considered as the phenotype,what type of inheritance does this represent?

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:

The phenomenon of incomplete dominance was observed by whom?
